Qualcomm Embedded Software Engineer interview questions

Interview consisted of an hour long initial phone screen and then a "round robin" interview with many other candidates. Interviews were both almost completely technical. They didn't seem interested in getting to know the candidates, only how they could perform under pressure and with technical problems. Phone interview (1 hr) (pure technical) Q: What is a watchdog timer? A: Correct Q: What is atomic programming/non-locking operation? A: Idk What is concurrency and multithreading? A: correct What is static keyword? A: correct What is volatile keyword? A: correct Programming problem (live) (reverse a linked list) A: correct In person interview (round robin, 4 interviews, 30 min each, whiteboard) I1: Add a new node to a linked list A: Mostly correct I2: Embedded systems questions, low level programming question using "malloc" A: Incorrect, did not perform well I3: Function that takes a 2d array of a "sudoku board", and checks to make sure it is a possible board. A: Mostly correct I4: Reverse string function, reverse words function, binary tree questions A: Correct

2 weeks after applying online I was contacted by the hiring manager for a technical phone screen. We went over pointers and simple function design/testing on a shared word document. 2 weeks later I went in for a full day interview at the Boulder campus. There were 13 other candidates there doing the same thing. I had (4) hour long technical interviews with different members of various teams and (1) half-hour long interview with HR. They fed us lunch and did a brief recruiting presentation. 2 weeks later they sent a generic email stating "Although we were very impressed with your background and qualifications, we are unable to offer you a position with Qualcomm at this time." Overall it seemed like they were more interested in finding book worms fresh out of school with no practical working experience than someone with actual embedded engineering experience. Make sure to study linked lists, linked lists, binary trees, and more linked lists because that is all they seem to care about!
