I applied via referral and got a HackerRank coding test link. There were two coding questions that I solved with ease. Got a call from a recruiter who asked me some basic screening questions and then told me there will be cohort hiring, which is 3 rounds of 45 min back to back within 3 hours. 1. The first round was a coding round. I was given an existing Java code; I had to review the code within 10 mins and share my findings. The given code looked a bit messy, but if you regularly write and review Java codes, it should be very easy. Then there was a coding question based on valid parentheses. I solved it within minutes, but the interviewer asked for an alternative approach , which I could not do; it was simple, but it didn't click at that time. 2. After a 15-min break, there was another round. I was asked a system design question. Made a rookie mistake of not cross-questioning the given problem but slowly designed a stable system. There were many cross questions and situations asked. I had to consider those in my design and had to answer the questions accordingly. 3. After another 15 min, there were leadership rounds. The interviewer asked some situational/leadership questions which I had to answer based on real-life examples. All the interviewers were very polite and helpful. It felt like an interview process rather than interrogation. However I find some of the recruiter sort of rude :P
