When an interview starts with a Junior Engineer asking about how to program a linked list on a whiteboard, you know its not going to be a good interview. For 5 hours I was repeatedly grilled on all areas of embedded computing; repeatedly the same questions. I was asked questions that not even the interviewer knew the answers to. Of the 5 people that interrogated me, non were the hiring manager. I was then taken to lunch by the hiring manager and 4 other interviewers. Instead of using the time to learn about me, the person, the hiring manager used this time to ask me things he knew I didn't know; or at least he should of by then from the comments of the others. While I choked down my grilled chicken, the questions got more ridiculous. After 6 hours of interrogation, my brain was numb. When asked about how to debug the registers of kernel core dump after a panic, I surrendered and simply responded with "Good question..."; hoping that the inferiority complex that the Manager had would end.... and it did. They dumped me at the curb in front of HR. No proper good byes exchanged. Good riddance. Even if I would have been offered a position, I would have refused.

Communicative interviewer. Really helped me throughout the process. HR was clear and was accommodating all my requests. Super helpful management. Questions were intriguing and needed a blende of in depth understanding and out of the box thinking.
