NVIDIA Software Developer interview questions

Had A decent interview not that good. I don't have anything else to tell.My interview is tomorrow. Prepare for oops, DBMS, OS, C/C++. Preparing for these subjects is more than enough

Interview was onsite. Met with several engineers to discuss experience. There was some general technical questions but was not asked to do any coding questions. Interview process lasted several hours. Recruiter never followed up with offer or rejection. Unprofessional.
