Lumileds Process Engineer interview questions

Online interview, interviewer was late and not turning on camera, did not ask to start, very quiet (or shy?) After briefly introducing myself, got no response, further add on introduction, still no response. Not paying attention to which degree courses I was graduated from, does not give a chance, just showing a very uninterested attitude and said "err... err... don't know what to ask you". Interview process was terribly short, maybe HR did not screen and allow everyone to attend interview. Additionally, a coursemate of mine got offer with the same position even though my degree was "not qualified/uninterested" and hers was "I'm sure with your good result, you can pick up very easily".

The first and last interview was a one to one interview with the hiring manager. I was called on the phone for the interview at the Lmileds office in Singapore. The HRM was really nice and guided me to the room. The hiring manager met me personally and took the interview that laster 49-50 mins
