Fujitsu Real-Time Embedded Software interview questions

I had an phone interview verifying my skill sets and working experience. It went well. After 1 week, I got an on-site interview. It took about 2 to 3 hours with a group of 5 or 6 people consisting managers and technical senior staffs. As far as I can remember, the questions are about the following topics: - C++, OO design, inheritance - platform, device driver - RTOS (paticular OSE), semaphore, priority inversion - knowledge of s/w architecture of your previous systems you worked on I heard that the working environment is friendly, process oriented and challenging schedule.
