NVIDIA SOX Compliance Intern interview questions

First scheduled a phone call with HR. The phone call was with the hiring manager. Just basic introduction of the role and why you want to work for NVIDIA. Then HR emailed me and wanted to schedule three phone calls. Two phone calls were with the team member and the last phone call was with the hiring manager. Each call is about 30 mins long. Didn't have much technical question. However as I was talking to one of the associate, I was asked about several accounting questions about A/R, depreciation, etc. The three phone calls are the final process. Overall process from end of Jan to end of Feb.
