I designed a tool during my research, and was asked to draw a detailed circuit diagram explaining each parts. Asked fundamental questions - internal energy, entropy, Gibbs free energy. If I could go back in time, would I change anything about my career path. Case: Design an efficient battery for a smart phone and explain its advantages over the existing technology.
If you spin photoresist on a wafer, what will be the difference if the wafer is very cold or very hot?
Everything went well. To be honest, I have no idea why they rejected me. I handled all questions from them pretty well. Tried to be chilled and social. My hypothesis is that they already hired somebody with similar background to me. Set up on site interview as soon as you can if you want the job (I delayed it on purpose for 1 month after phone interview).
Are you willing to be a tool owner as a process engineer?
How does x-ray diffraction work? This was an easy question, but unexpected.
Describe to me briefly about your research in two minutes!--This one was particularly hard not because I do not know my own research, but its hard to express all the intricate details of 5+ years of work that I have done in 2 minutes!
What do you say to your advisor when you don't meet his/her expectations in terms of your research/experimental goals for the week? How did you deal with it? Explain to me what instruments/tools you are/were in charge of during your PhD. What did you have to do to maintain the instruments? Did you ever have to fix it yourself?
What is the difference between a metal and semiconductor? What is activation energy?
Few technical questions in the phonescreen interview. Technical questions were all related to my dissertation.
