@OP: I am a PhD holder as well and I have years of industrial experience. Situations similar to this unacceptable behavior happened to me as well during my early years at Qcom. It came from the tech lead, not from my manager, who was always rude and condescending. At that time I didn't know why this person was targeting me, I was always pleasant to him. I tried to be always nice and professional while dealing with him hoping my actions would make him change, but I was mistaken. I also was on H1B visa at that time so I didn't want to cause a lot of trouble to myself and lose my status. We all know how tricky and miserable being on H1B visa status. That tech lead knew my visa status as well and gave him more power over me. He was on H1B visa himself at some point. Fast forward I left that group because things just kept getting worse. I heard that the same tech lead found another target after I left who was also a PhD holder on H1B visa. Someone told us that tech lead attempted to get his PhD a while ago but he failed so he was so envious of anyone with PhD. That explained a lot.
Anyways, here is what I think you should do:
If you are on H1B visa then s— it up till you find another job and try to avoid that manager. Don't be fool and expect things to get better if you do a great job and become nicer to him. He will just treat you more poorly and you will become his little beach.
Don't go to the HR, it is a big mistake that I did. I repeat DON'T go to the HR. They are not there to protect you, HR people are not your friends, their job is to protect the company from lawsuit. What HR would do is comforting you while talking to your manager behind your back to prepare to kick you out blindsided.
If you are a permanent resident or US citizen then I would say fight back and kick that SOB in the balls in front of everybody. Collect as much information as you can to protect yourself and use it against the company if things go sour. DON'T GO TO THE HR...Geez!!!
What I came to realize as a life lesson is that bullies will never treat you better as you become nicer to them, it is the other way around actually. Bullies prey on weak, once you show them you are capable of fighting back they will back off and find another weak prey. Bullies are weak from the inside, you need to put them in their place early on. Unfortunately Qualcomm is full of those insecure bullies at all levels.
