One of their recruiters got in touch with me on linkedin. They were looking for someone with device driver background. After a few emails back and forth, they decided to bring me in their office instead of the regular phone screening. Initially I was told that this was still a screening process before the actual interview. I thought it was strange to have a screening process that lasted 5 hours. The questions were fairly generic like how do you reverse a linked list, dma vs io etc. There weren't any trick questions. They were all nice people but I felt there was a disconnect between them and the recruiter that was arranging the interview. Some of them didn't know what position I was interviewing for. I was under the assumption that I will be called for the next round of interview and then the recruiter called me and said that they are extending an offer to me. I was surprised at the turn of events but relieved that I didn't have to repeat the same things again for another few hours. The offer they extended me was probably good in market value, but they were barely able to match what I was making in terms of base salary. Their USP seems to be the restricted stock that they offer people. It would have been a nice match for me except that I got an offer in an early stage startup which promised me much better equity(Apples and oranges again). Overall, the experience was highly positive.
