3 rounds of interview first round is coding round taken by a principal engineer who asked a complex coding question not DSA but take complex json input parse it flaten it and make weighted average of the inputs and provide a output in a different format

Interviewed in summer 2024. Talk with screener about job, role, etc. First stage was talk with Hiring Manager about exp. Second's home work, create backend service using their reqs, nothing complicated but time consuming. 3d stage arch decision talk with one of the engineers from target team (also security related questions, basic topics without depth). 4th and last interview was with Head of Department or some similar role, std behavioral questions, motivation talk, etc. Didn't pass last stage, reason unknown. 1.5 mos from first contact to the end. Neutral since last stage was terrible, weird talk, ghosted results (before were responsive).

Took 6 weeks for a single interview then never heard from again. Would wholeheartedly not recommend them to anyone ever. This is just too much for anyone to have to go through.
