Quick Stats

Applied through TCS's campus recruitment in December 2026. Being one of India's largest IT companies, the process was structured and followed a standard pattern. From application to offer took about 3 weeks — typical for TCS.

Round 1: Online Assessment

Format: 90-minute aptitude + technical test Duration: 90 minutes What they were testing: Aptitude, Java fundamentals, microservices concepts Interviewer approach: Automated

The assessment had 3 sections: aptitude (quantitative, verbal, logical), Java-specific MCQs, and 2 coding problems. The coding problems were medium difficulty — one involved implementing a REST API endpoint, another was about microservices communication patterns.

I think the aptitude section was weighted more heavily than I expected. TCS, like other IT services companies, seems to value overall problem-solving ability as much as technical skills.

Round 2: Technical Round

Format: 60-minute video call Interviewer: Senior Java Architect Duration: 55 minutes What they were testing: Java, Spring Boot, microservices architecture Interviewer approach: Traditional — asked questions from a prepared list

The interviewer started with Java basics: Spring Boot annotations, dependency injection, and microservices patterns. Then moved to Spring Cloud — service discovery, API gateway, and circuit breakers.

I was asked to design a simple microservices architecture for an e-commerce application. I proposed separate services for user management, product catalog, and order processing, with Spring Cloud Gateway for routing and Eureka for service discovery.

His exact words were something like, "How would you handle distributed transactions across these services?" I discussed saga patterns and eventual consistency. He seemed satisfied with the approach.

Round 3: HR Round

Format: 30-minute video call Interviewer: HR Manager Duration: 25 minutes What they were testing: Communication, willingness to relocate, career goals Interviewer approach: Standard HR questions

This round focused on why I wanted to work at TCS, my experience working in IT services, and my career goals. I emphasized my adaptability and interest in working with different technologies and clients.

The HR manager asked about my comfort with the on-site work model — was I willing to work from their Mumbai office? I said I was comfortable with that and appreciated the structured environment.

The Insider Section

Here's something most guides don't mention: TCS puts a lot of emphasis on client-facing skills and project flexibility. In my technical round, the interviewer asked how I'd explain microservices concepts to a non-technical client. They're not just looking for coders — they want people who can communicate with business stakeholders.

Also, they're big on certifications. The interviewer mentioned that TCS encourages employees to get certified in Java, Spring, and cloud platforms. Having certifications can help with faster career progression in their structured environment.

Compensation

The offer was ₹15 LPA base with a ₹2 LPA performance bonus. For a Java Microservices role in Mumbai in 2026, this is standard for TCS. The compensation grows significantly with experience, certifications, and project complexity.

Honest Assessment

Who this role IS right for:

• Engineers early in their career who want structured learning
• People interested in working with multiple clients and technologies
• Those comfortable with on-site work and IT services environment

Who this role ISN'T right for:

• Someone looking for rapid career growth through levels
• Engineers who prefer product development over client projects
• People who want to work on cutting-edge technology exclusively
