Qualcomm

You can do a lot of work without getting paid much.

Qualcomm HR is really, really bad, and they try to take advantage of people. That's why they always go and hire people from companies who have recently laid off people because, in desperate times, people are ready to take up any position and at any salary. They specially do that with internationals working here. I have not seen any other similar company do this.

Qualcomm wants you to work all day and night and then doesn't want to reward you for it, not even a pat on the back.

They have tons of directors. Yes, Qualcomm likes to give lofty positions to people, and they have so much hierarchy in terms of positions that a person joining at a lower level feels like a useless worm here.

The so-called upper management never cares to talk to employees.

Promotion system is totally vague and seems highly unjust.

Keep an eye on what your hiring people are doing. Reward people based on their work and not if they are friends with you. For goodness sake, talk to everyone under you once in a while at least.
