I had a phone screen with a gentleman whose name I never did correctly get. He asked good C/debugging questions, but he was very combative and when I asked if I could ask a question, I was told no and he continued to ask questions. I knew I only did so-so, but I never heard back from SanDisk. It must be a sweat shop. I'm glad I landed somewhere else.

I was asked technical questions most of which were not deep neither were specific. They were mostly open ended questions which a suitably experienced person can answer without preparation. My tip is that you keep talking and they will take you if they feel like.
