I applied for an interview through my school's career center and went through two rounds of interview.
The 1st interview was an on-campus interview with the president of the company. He asked me questions about my resume along with a couple behavioral/personality based questions.
2nd Round of interviews was on site. They paid for my trip up to Goleta and took me out to dinner. It was quite awesome. The next day, I had an interview with the VP and HR manager in the morning. Had lunch with the president (ASK QUESTIONS/ HAVE A DECENT CONVERSATION). Went back to the office and had another interview with the manufacturing and product development team leads. Again, most of the questions were personality/resume/behavior based.
It's not a high pressure situation. Everyone was extremely nice and friendly.
