NVIDIA interview questions

Total 3 round happened in a day, 2 round were python coding round and 1 round by HR Questions were interesting, I could answer most of the question. Still I didn't get job offer

The phone screen was average but had too many puzzles. The 5 f2f interviews were on projects, SV and UVM but the interviewers always take you away from your area of expertise. That's okay to some extent but annoying if concrete questions are asked for which one needs to consider many factors, apart from what the interviewer had in mind, to select a correct implementation. The interviewers want a clever answer not the correct one. Also some of their questions are vague and they will expect you to find all the unasked,implicit sub questions and solutions. Then will interrupt your explanation to go off on another tangential detail before you finish. In programming and methodology interview where they wanted to know details found in nooks and crannies of reference manuals. dismissive of implementations other than their own even when pros and cons are outlined. On top of that sophomoric puzzles /cs algorithm questions are tossed out in midst of serious discussions. Seems they want people who spend their time looking up puzzles and appearing smart.To deal with the interview one would need everything from asic design(rtl and gate level) to verification to data structures/algorithms. Mostly asic interviews are enjoyable irrespective of rigor or result but this one was too tiresome. Looks like this style of interviewing has become a fad.
