Onsite IV3 Product Architecture

1. design a coding contest platform - I feel like I messed this one up - couldn't discuss the complete HLD, because I ran out of time and went into the deep dive of how isolation would work

Onsite IV 4 Behavioral
Don't remember many questions from this round - just the usual fluff - Honestly can't judge how this round went.

Onsite IV5 Coding
iv4 -

1. sparse vector multiplication
2. merge intervals

All my coding rounds were good, I might've missed some test cases - some bugs might've been pointed out by the interviewer in two/three questions but overall it was fine. I believe Product Arch/Behavioral was the reason for reject for me. Got an email ~10 days later that I didn't make it and the cooling off period is 12 months. Pretty bummed out about it but I have another offer so it's ok.

Best of luck for whoever is preparing.
