A standard whiteboard interview where they asked me a bunch of algorithms/data structures questions. They also went over my Grades Sheet as I was recent graduate back then. Asked some questions about open source contributions and described their jobs and what I'm expected to do.

NVidia has an internal EDA/CAD tool development group. I had a call from recruiter & he described about work, & asked for conducting interview. I agreed. Had 1st tele round with manager of cad group. Main focus had been on netlist designing, traversals & some other DS/algo. Then i had a 2nd tele round with a senior from Santa Clara, where focus had been again on netlist structure & problems/solutions related to that area. Thereafter, i had been called for F2F round at bangalore. There i had 4 rounds, first 2 rounds were technical rounds, where problems related to DS/algorithms were asked. Then, after lunch, 3rd round was focused around puzzles. Finally 4th round was a technical discussion with manager. In this, we discussed, profile/work requirement & company discussion, also discussion around company requirement. Then he discussed about my candidature , my past work experience. Finally discussion ended with mutual discussion around requirements of each other. After that, HR told me that they will give an offer in a few days. Around a week later, i got the compensation breakup & offer.
