Panasas Kernel Software Engineer interview questions

Got a call from recruiter then had a technical phone screen which mostly concentrated on kernel fundamentals like synchronization and memory management. Got called for an onsite interview which had 4 interviews which were an hour long. The questions ranged from design issues where I had to implement framework APIs that other kernel components can use to get high resolution timers and also some algorithmic questions. Overall the interview process was good and relevant to the positions.
