How to Transition from Indian IT Services to a Product Company Abroad

I'm going to tell you this story because it's one I hear variations of constantly, and if you're reading this article, you're probably living some version of it right now.

You're at Infosys. Or TCS. Or Wipro, HCL, Cognizant, Tech Mahindra — pick your flavor. You've been there three, five, maybe seven years. You're a "lead" or a "senior consultant" or whatever title your company uses that sounds impressive but doesn't map to anything the outside world recognizes. You've worked on multiple client projects. You've managed teams. You've hit your billable hours targets. You've gotten decent appraisals.

And you know, in a way that's hard to articulate to people who haven't been through it, that you're stuck. Not in a dramatic, crisis way. In a slow, creeping way. Your salary increases are 8-12% per year. Your work is maintenance, support, or building features that someone else designed. You're not making technical decisions — you're implementing technical decisions made by architects at the client company. And when you look at your friends who went to product companies — the ones at Google, Amazon, Flipkart, Stripe — you see them doing completely different work. They're designing systems. They're owning products. They're growing at a different velocity.

So you want to make the jump. From IT services to product. From implementing someone else's vision to building your own. From a company where you're a resource to a company where you're an engineer.

Here's the honest truth: it's possible. I've seen it happen dozens of times. But it's harder than most people think, it takes longer than most people want, and there are specific things you need to do — and stop doing — to make it work.

Acknowledging the Gap

Before I talk about how to close the gap, let me be honest about what the gap actually is. This isn't to discourage you. It's so you know what you're dealing with.

The typical Indian IT services experience, especially at the large companies, develops certain skills very well: working with clients, meeting deadlines, working within established systems, adapting to different technology stacks, managing teams, and handling the administrative overhead of large projects. These are real, valuable skills.

What IT services typically does NOT develop well: designing systems from scratch, making architectural decisions, writing production-quality code (as opposed to code that "works"), understanding why certain technical approaches are better than others, owning a product end-to-end, writing tests (real tests, not the kind you write after the fact to hit a coverage metric), contributing to open-source projects, or thinking about user experience.

The hiring bar at most product companies — and I'm talking about companies like Google, Amazon, Microsoft, Meta, Stripe, Uber, Airbnb, but also mid-tier product companies — is calibrated around the second set of skills. When they interview you, they're testing your ability to solve algorithmic problems (data structures and algorithms), design systems at scale (system design), write clean code (coding rounds), and communicate your thinking clearly (behavioral rounds). The IT services background prepares you for maybe one of those well (communication, if you've done client-facing work) and the other three poorly or not at all.

This is not because you're not smart enough. Let me be very clear about that. The people at IT services companies are, on average, just as intelligent and capable as the people at product companies. The difference is training and environment. If you spend five years executing against requirements documents rather than designing solutions, your system design muscles atrophy. If your codebase at work is a million-line Java monolith with no tests, you don't develop testing habits. If your daily work is maintenance rather than creation, your problem-solving sharpness dulls.

The gap is real. But it's a gap of practice, not ability. And practice gaps can be closed.

The Technical Preparation

Let me walk through what you actually need to study, in rough priority order.

Data Structures and Algorithms (DSA): This is the gateway. Every product company interview starts with DSA rounds, and if you can't pass them, nothing else matters. The IT services background usually means you learned DSA in college, never used it at work, and forgot most of it. You need to relearn it and practice extensively.

Here's my recommended approach: Start with Neetcode.io's roadmap. It organizes LeetCode problems by pattern, which is much more effective than just grinding random problems. Do the "Neetcode 150" list. Aim for 2-3 problems per day, spending no more than 30 minutes on each before looking at the solution. Focus on understanding patterns (sliding window, two pointers, BFS/DFS, dynamic programming, binary search) rather than memorizing solutions. You need to reach a point where, given a new problem, you can identify the pattern and apply it within 15-20 minutes. This takes most people 3-6 months of consistent practice, doing problems at least 5 days a week.

If you haven't done competitive programming and the idea of LeetCode scares you, start with easier resources. "Grokking the Coding Interview" on Educative.io is excellent for pattern-based learning. Abdul Bari's YouTube channel explains algorithms better than most textbooks. The goal is to build confidence before jumping into the harder problems.

System Design: This is where IT services experience can actually be a partial advantage, because you've worked with large, complex systems — you've just been implementing them rather than designing them. What you need to develop is the ability to design a system from requirements, making tradeoff decisions along the way.

Start with "Designing Data-Intensive Applications" by Martin Kleppmann. Read it cover to cover, even if some chapters are dense. It's the best single resource for understanding how distributed systems work. Then move to system design interview resources: Alex Xu's "System Design Interview" books (Volume 1 and 2) are the standard references. Gaurav Sen's YouTube channel is excellent for visual explanations.

Practice by designing systems on paper or a whiteboard. How would you design Twitter? A URL shortener? A ride-sharing service? A payment system? Practice explaining your design out loud, because in the interview you'll need to think and communicate simultaneously. Record yourself explaining a system design and listen back — it's painful but effective.

Object-Oriented Design and Code Quality: Product companies care about how you write code, not just whether it works. This means clean code principles, SOLID design, proper abstraction, meaningful naming, error handling, and testing. If your IT services codebase was a mess (and honestly, most are), you need to unlearn some habits.

Read "Clean Code" by Robert Martin. Read "Refactoring" by Martin Fowler. But more importantly, write code on personal projects and get it reviewed. Contribute to open-source projects on GitHub — even small contributions like fixing bugs or improving documentation will expose you to codebases that follow good practices and reviews from engineers who care about code quality.

One Modern Tech Stack, Deeply: IT services often means you've touched ten different technologies but aren't deep in any of them. For product company interviews, you need to be truly strong in at least one stack. Pick one and go deep. If you're a backend engineer: Python + Django/FastAPI or Java + Spring Boot or Go. If you're a frontend engineer: React + TypeScript. If you're into data engineering: Python + Spark + SQL. Know your chosen stack well enough to build a non-trivial application without looking up basic syntax.

The Resume Problem

Here's where a lot of IT services professionals sabotage themselves without realizing it. Your resume is probably structured wrong for product company applications.

The typical IT services resume reads like this: "Worked on [client project name] using Java, Spring Boot, Oracle, and Jenkins. Responsible for development and maintenance of [module]. Coordinated with offshore team. Delivered project on time."

A product company recruiter reads that and thinks: "Okay, but what did you actually do? What problems did you solve? What was the impact?" There's no signal in that description that distinguishes you from ten thousand other IT services professionals with similar backgrounds.

Your resume needs to be rewritten to emphasize outcomes and technical decisions, not activities. Instead of "Developed features for payment module using Java and Spring Boot," write "Redesigned the payment retry logic to handle intermittent gateway failures, reducing failed transactions by 23% and recovering approximately $140K in monthly revenue." Instead of "Managed a team of 8 developers," write "Led a team that migrated a monolithic billing system to microservices, reducing deployment time from 4 hours to 15 minutes."

If you don't have metrics, estimate them. If your work really didn't have measurable impact — which is common in IT services — then you have a bigger problem, and the answer is to start doing work that has measurable impact. More on that in a minute.

Also: remove the jargon that screams "IT services." Terms like "onsite coordinator," "offshore delivery," "resource allocation," "billable utilization" — none of these mean anything to a product company and some of them are actively negative signals. They tell the reader that your experience is in the services model, which, fair or not, carries a stigma in the product company world.

The "Bridge" Companies Strategy

This is the strategy that I think is most practical for most people, and it's the one I recommend most often. The idea is that you don't jump directly from TCS to Google. You make an intermediate stop at a "bridge" company that falls between IT services and top-tier product companies in terms of hiring bar, work culture, and resume signal.

What are bridge companies? Here are some categories:

Mid-tier product companies: Companies like ServiceNow, Salesforce, VMware, Atlassian, Intuit, PayPal, Cisco, Oracle (the product side, not consulting), SAP. These companies have lower hiring bars than FAANG but significantly higher bars than IT services. They'll give you real product engineering experience, better coding practices, and a resume line that product companies respect.

Large tech companies' less competitive teams: Amazon has hundreds of teams and some are much easier to get into than others. Amazon's AWS support tools teams, internal tools teams, and some of the retail operations teams hire people from IT services backgrounds more readily than the core services teams. Same with Microsoft — some Azure teams, Dynamics 365 teams, and enterprise product teams are more accessible entry points. Once you're inside a big tech company, internal transfers are much easier than external hires.

Well-funded startups (Series B-D): Startups at this stage need to scale their engineering teams and are often more flexible on pedigree than established companies. They care more about "can you build things quickly" than "did you pass a six-round interview." Companies like Razorpay, Freshworks (before they went public), Swiggy, and PhonePe in India have been great bridge companies for people moving from IT services. In the US, there are hundreds of similar-stage startups hiring actively.

Indian product companies with US offices: Companies like Freshworks, Zoho, Postman, Browserstack, and Chargebee have engineering teams in both India and the US. Getting into their India office from IT services is more achievable, and once you're there, you can potentially transfer to the US office or use the experience on your resume to apply to other US companies.

The bridge company strategy works because it solves two problems simultaneously: it gets you real product engineering experience, and it gives your resume a signal that product company recruiters recognize and respect. Two years at ServiceNow followed by an application to Google is a very different story than seven years at TCS followed by an application to Google.

Building Your Portfolio While Still at IT Services

You can't quit your job tomorrow and start studying full-time (well, most people can't). So the question is: what can you do while you're still at your current company to prepare for the transition?

Side projects are non-negotiable. You need to have at least one substantial project on your GitHub that demonstrates your ability to design and build something from scratch. Not a tutorial clone. Not a to-do app. Something that solves a real problem, uses a modern tech stack, includes tests, has decent documentation, and is deployed somewhere. This is your proof that you can do more than what your job requires. If you can't think of an idea, look at open-source projects in a domain you're interested in and build something that integrates with or extends them.

Contribute to open source. Find a project that's related to the technology you want to work with and start contributing. It doesn't have to be huge contributions. Fix a bug. Improve documentation. Add a feature that users have been requesting. The process of contributing to open source — reading others' code, following contribution guidelines, going through code review, dealing with CI/CD pipelines — teaches you things that IT services never will. And it's visible, public evidence of your skills.

Internal innovation projects. Most large IT services companies have some version of an innovation lab, hackathon, or internal projects initiative. Use these opportunities. Volunteer for the projects that involve building something new rather than maintaining something existing. Even if the project itself isn't impressive by product company standards, the experience of ideating, designing, and building from scratch is valuable preparation.

Switch teams or projects internally. If you're on a maintenance project, request a transfer to a team that's building something new. If you're doing testing, move to development. If you're working with legacy technology, find a project that uses modern tools. The specific project you're on within your IT services company matters more than people realize — "I built a new microservices-based platform for [client]" is a much better story than "I maintained a legacy CRM system."

The Timeline: Be Realistic

How long does the transition take? I wish I could tell you it's quick. It's not.

If you're coming from 3-5 years at an IT services company with a CS degree and decent fundamentals: expect 6-12 months of serious preparation (DSA practice, system design study, side projects) before you're competitive for mid-tier product company roles. Add another 1-2 years at the bridge company before you're competitive for top-tier roles. Total timeline: 1.5-3 years.

If you're coming from 5-10 years at IT services with rusty fundamentals: expect 9-18 months of preparation for mid-tier roles. The preparation takes longer because you have more to relearn and less time available for studying (family, visa obligations, etc.). Total timeline: 2-4 years.

If you're coming from 10+ years at IT services: the path is still possible but it's different. At this level, you're likely targeting engineering management or senior architect roles rather than individual contributor roles. The interview process is more focused on system design, leadership, and strategic thinking than on DSA. But the gap in product thinking and modern engineering practices is often larger, so the preparation is different — more about building product intuition and less about LeetCode grinding.

These timelines assume consistent effort. Not casual, weekend-only studying. Not "I'll get to it when work is slow." Dedicated, daily practice. 1-2 hours on weekdays, 3-4 hours on weekends. It's the equivalent of a part-time degree in terms of effort, and the results are similar — it seriously changes your capabilities and marketability.

The Interview Differences

If you've only ever interviewed at IT services companies, the product company interview process will be a shock. Let me prepare you.

IT services interviews are usually: talk about your experience, answer some basic technical questions, maybe a short coding exercise or debugging task, and a discussion about your availability and expected salary. The whole process takes one or two rounds and a few days.

Product company interviews are: a recruiter screen (30 minutes, checking for basic fit), a phone screen or online assessment (45-60 minutes, usually one or two coding problems), and then an "on-site" loop (4-6 rounds over one day, covering coding, system design, behavioral/leadership principles, and sometimes domain-specific questions). The whole process takes 2-6 weeks and is designed to be exhausting. They're testing not just your knowledge but your ability to perform under pressure over an extended period.

At Amazon namely, which is probably the most accessible FAANG company for IT services professionals, the behavioral interview round (called "Leadership Principles" or "LP" round) is weighted very heavily. You need to prepare 15-20 stories from your career, structured in the STAR format (Situation, Task, Action, Result), that map to Amazon's 16 Leadership Principles. This is one area where IT services experience can actually shine — if you've worked with difficult clients, managed team conflicts, delivered under tight deadlines, or made decisions with limited information, you have stories to tell. You just need to structure them properly.

For Google and Meta, the technical bar is higher but the behavioral component is less structured. They care more about your ability to solve novel problems than your stories about past experiences. This means heavier DSA and system design preparation.

For startups, the process is more variable but often includes a take-home project or a pair programming session where you build something together with an engineer from the team. These can actually be easier for IT services professionals because they test practical building ability rather than competitive programming skills.

The Money Conversation

Let me address this directly because it's a real concern. When you're making 15-25 lakhs at an IT services company in India, the idea of spending 1-2 years preparing for a job that might not materialize is financially daunting. And if you're on an H1B or looking at international opportunities, the stakes are even higher.

Here's the math that might motivate you. A mid-level engineer at an Indian IT services company makes roughly $15K-$25K per year. A mid-level engineer at a US product company makes $150K-$250K per year in total compensation. Even accounting for the higher cost of living in the US, the gap is massive. Over a 10-year career, the cumulative difference is easily $1 million or more. The 1-2 years of preparation is the highest-ROI investment you can make.

Even staying in India, the gap is significant. A product company in Bangalore pays 30-60 lakhs for mid-level engineers, compared to 15-25 lakhs at IT services. A transition from TCS to Flipkart or Razorpay or Google India could double your salary immediately.

The financial argument for making this transition is overwhelming. The question is never "is it worth it?" The question is "can I stick with the preparation long enough to get there?"

Staying the Course

Let me end with this. The hardest part of this transition isn't the studying. It's the sustained effort over months, sometimes years, while dealing with all the other parts of your life — the demanding day job, the family obligations, the visa uncertainty, the self-doubt that creeps in at 11pm on a Tuesday when you've been working all day and then spent two hours on LeetCode and you still can't solve medium-difficulty dynamic programming problems.

I've seen people give up three months in. I've seen people give up after their first round of rejections. I've also seen people who took two years, got rejected from fifteen companies, and then landed at Amazon or Microsoft and never looked back. The difference wasn't talent. It was persistence.

Here's what helps: find a community. Join a study group — there are dozens of active ones on Discord, Telegram, and Reddit particularly for Indian engineers preparing for product company interviews. Having people who are on the same journey makes the hard days easier. Get a study buddy and hold each other accountable. Share your progress publicly — there's no better motivator than knowing other people are watching.

And give yourself permission to take breaks. You're not training for a sprint. You're training for a career change that will define the next twenty years of your professional life. A week off when you're burned out is not failure. It's sustainability.

The path from IT services to product company is well-trodden. Thousands of Indian engineers have walked it before you. Some of the best engineers I've worked with at product companies came from Infosys, TCS, and Wipro. They'll tell you the same thing I'm telling you: it was hard, it took longer than they expected, and it was absolutely worth it.
