WD Principal Staff Engineer - Firmware interview questions

Classic 5 - 50 minute interviews, 2 with managers, 3 with engineers. Dropped me in a conference room and ran the interviewers through it. Some coding questions, some algorithm questions. Most of the questions were about how I'd deal with particular problems customers had and how to approach them from a business and technical direction. One of the interviewers didn't show up, so I had a break in mid-stream that wasn't expected.
