Quick Stats

Applied through Tata 1mg's careers portal in January 2026. A recruiter reached out within a week. The process took about 3 weeks — typical for a healthtech company at this scale. Being part of Tata Digital, the process was structured and thorough.

Round 1: Online Assessment

Format: 75-minute coding test Duration: 75 minutes What they were testing: Problem-solving, Java fundamentals, healthtech awareness Interviewer approach: Automated

The assessment had 3 coding problems. One was about implementing a medicine inventory management system — fitting for a healthtech company. Another involved designing a prescription validation API. The third was a standard DSA problem about order processing.

I think the healthtech-specific problems made this assessment more interesting than standard coding tests. They clearly test for domain awareness, not just generic coding skills.

Round 2: Technical Round

Format: 60-minute video call with shared coding Interviewer: Senior Backend Engineer Duration: 55 minutes What they were testing: Java, Spring Boot, microservices, healthtech systems Interviewer approach: Practical — focused on real Tata 1mg problems

The interviewer started with a warm-up: "Tell me about a challenging backend system you've worked on." I talked about implementing an order management system at my previous company.

Then we moved to coding. The problem was: implement a simple prescription processing service that can validate drug interactions and check inventory. I had to handle validation logic, database operations, and error handling.

I used Java with Spring Boot and implemented service layer logic with proper validation. The interviewer pushed me on edge cases — what about drug-drug interactions? How do you handle out-of-stock scenarios?

His exact words were something like, "How would you scale this to handle millions of prescriptions per day?" That's when I brought up microservices architecture, caching strategies, and database sharding. He seemed satisfied that I understood the scale challenges.

Round 3: Managerial Round

Format: 45-minute video call Interviewer: Engineering Manager Duration: 40 minutes What they were testing: Culture fit, problem-solving, Tata values Interviewer approach: Behavioral — focused on leadership and collaboration

This round was about my experience working in healthcare technology, my approach to building reliable systems, and my alignment with Tata's values. I shared examples of how I'd handled data privacy and compliance at my previous company.

He also asked about my comfort with Tata's structured environment — how do you work within large organizations? I emphasized my adaptability and focus on delivering value at scale.

The Insider Section

Here's something most guides don't mention: Tata 1mg puts a lot of emphasis on understanding healthcare compliance and data privacy. In my technical round, they asked about handling patient data securely, HIPAA-like compliance in India, and drug regulation requirements. If you haven't worked in healthcare, you'll need to do significant homework.

Also, being part of Tata Digital, they care deeply about system reliability and patient safety. The interviewer asked about handling critical failures, data backup strategies, and ensuring 99.9% uptime. They're not just looking for code that works — they want systems that can handle healthcare-critical scenarios.

Compensation

The offer was ₹32 LPA base with a ₹4 LPA performance bonus and ESOPs. For a Software Development Engineer role in Gurugram in 2026, this is competitive with other top healthtech companies. The ESOP component was attractive — Tata 1mg has significant growth potential in the digital health space.

Honest Assessment

Who this role IS right for:

• Engineers interested in healthcare technology and patient impact
• People who enjoy working on mission-critical systems
• Those comfortable with large, structured organizations

Who this role ISN'T right for:

• Someone looking for rapid experimentation and fast product iteration
• Engineers who don't care about healthcare compliance and data privacy
• People who prefer complete autonomy over structured processes
