i was invited for the interview after I submitted my Phd thesis. First is manager interview, followed by director interview and HR. The process was quite relax, no much about technical questions, it was more on what I worked on during my Phd study and what your exceptions about your job and what is my long term plan here

Basic of semiconductor devices from diode to MOSFET . They also asked simple Qwes regarding circuit. Very chill guys. I cleared 2 rounds but was rejected on the basis of resume comparison.
