Research Electro-Optics interview questions

It started with a phone conversation with the recruiter. 5 interviews were scheduled for an afternoon and I was able to complete 3 that day. 2 did not participate and I returned another day for the final review. Everyone was very pleasant and the company is making products that are critical to the day-to-day lives of so many. I was not offered a position but wish them nothing but the very best.
