2 rounds of DS Algo, 1 LLD round, 1 HLD round, 1 Hiring Manager round - Medium/Difficult questions in DS Algo. Require clarity in class design, separation of concerns in LLD. Require knowledge of different systems, their applications and shortcomings for HLD round.

Total 5 rounds. 2 coding round. 1 coding + LLD round (2 hours) long, 1 HLD round, 1 Hiring manager round. 1. I did solve all the problems in both the coding round. Positive experience. 2. 3rd round just freaked me out, they sent invite for 1 hour long interview with title as "coding round" and ended up with 2 hours long coding + LLD round (I was too frustrated that I wanted to bang my head on table). Interviewer didn't even explain the expectation of interview as well (whether it will be coding or ). He blindly asked a problem which is purely coding and when I solved them he told me write LLD which was pretty late. He took 2 hours long interview. I had other interview scheduled which I missed because of this interviewer. Extremely negative experience. 4. 4th HLD round - positive experience. 5. 5th HM round - neutral experience. HM was asking me to pen down a *deterministic mathematical equation* for some "ad related problem". He was also eating chai pakora while interviewing me. (No professionalism) Overall: Negative Experience. Interview Recommendation: Only go for interview if you've lots of lots of patience to spend 2 straight hours for an interview.
