NVIDIA Software Engineer interview questions

I was contacted by NVIDIA in the first part of November of 2021. After a lot of interviews and waiting I got a job offer on January 7h. After that recruiter send me an email every week or two in which he told me they are hiring too many people and that I need to wait couple of days to sign the papers. This lasted for full 3 months after which I send an email that I'm not interested anymore. Highly unorganized company. You have to wait more than a week to get an answer to an email. HR is a mess

Got contacted by a recruiter and had an interview within a week. Interview covered data structures and projects I had been working on. Took in total 45-60 minutes, as planned, and was done through voice call.
