They asked a lot of basic concept about Photolithography and semiconductor. Entire process is quite tense and last for about half an hour. No response after that, so i thought i was rejected.

This was my first round of interviews. I got asked about Rayleigh's criteria. Losses that can occur in a semiconductor junction and a ton of behavioral questions like describe a time when you struggled in working in a team. How did you get out of a difficult problem?
