NVIDIA interview questions

I was interviewed at college campus.Process took 1 day.Firstly their was a test consisting of c/c++ ,DS,OS,quantitative aptitude questions.Later some of them were shortlisted interview process consisted of Coding Test(easy) 2 rounds of technical 1 HR round

Submitted resume and cover letter online and received an email within three days to set up a phone interview. It was relatively straight forward and they invited me to the campus. I met with at least six people to discuss my background and experience. I prepped a lot and the interview ended up being easier than anticipated. Left on good terms and hiring manager told me to expect a call the following week. Unfortunately they told me they had a hiring freeze and the requisition was placed on hold. No offer.
