The process took one day. A recruiter reached out to me. There were five rounds in total, and they were on an elimination basis. This meant that if I didn't clear round four, I wouldn't get to round five.

Overall, the process was great, but I'm not sure why I didn't receive an offer. I correctly answered all questions in all rounds and made it to the final HR round.

R1) General CS fundamentals - DBMS, Networks, Operating Systems, Cryptography, etc. For this, you have to know your engineering syllabus thoroughly.

R2) Implement an LRU Cache using Python.

R3) Design a URL shortener service like bit.ly. This was almost like a system design interview; however, I was not expected to actually sketch out the architecture.

R4) Problem-solving round - I was asked how I would approach the traffic congestion problem in a crowded city. This wasn't a coding/technical round at all. It was more like a brain teaser round and was meant to understand my problem-solving skills.

R5) Final round with the Engineering Manager. I was quizzed about my background, projects, internships, etc.
