Case Study Round
It was an AI Interview only, on their platform itself. I was asked total 20 case study based questions on Java, Microservices, Kafka, Redis, Load balancing, Spring Security. I was given only 1 minute per question, means only 20 minutes. I cleared this round, don't know how, even when I vaguely answered most of the questions.

It was taken on HackerRank platform, needed me to have an account already existing. They told me to solve 2 medium level questions there, first one was on printing long factorial of a number, the solution involved using BigInteger. Second question was printing time in words, i.e. 5:45 -> quarter to 5, and similarly for other times in English. I was given total 30 minutes total. I cleared this round.
