I applied online and the process took 3 days - interviewed at Qualcomm in April 2013.

Interview Details – I applied online, received an email to schedule a phone interview, and the manager I worked for was the one who phone interviewed and hired me. I had other offer deadlines approaching, so I called him back the next day and asked if the decision could be made quickly. The next morning, I got the call getting the position.

Interview Question – Extremely easy interview, asked basic programming concepts such focusing on object oriented design (Describe OOP, what is a class, what is a mutex, etc.).   Answer Question

I applied through college or university and the process took 3 months - interviewed at Qualcomm in March 2014.

Interview Details – Met through a college career fair. I heard back a few weeks later and started the interview prices. Depending on your recruiter, you sometimes have to stay on top of things and keep asking about interviews, especially if you're looking for one on campus. That said, my recruiter was exceptionally nice and helped with any questions I had.

Interview Question – Really just a few of the typical CS interview questions (I think it was the counterfeit coin question and maybe a few basic questions about C).   View Answer

I applied through college or university and the process took a day - interviewed at Qualcomm.

Interview Details – Recruiting came to my school and I handed in my resume at an infosession. Was selected for an on-campus interview. The questions were fairly straightforward, nothing unexpected. This a few years ago so I don't remember all of the questions. The only question I remember was how to reverse a linked list. There was also a bit manipulation question.

I applied through college or university and the process took 2 weeks - interviewed at Qualcomm in October 2013.

Interview Details – I was offered an interview on campus. It was just one round. I talked to a software engineer for about an hour discussing some general technical knowledge questions that ranged from object-oriented design to operating systems to reading code and understanding what it does. I also had a question showing me some variations of how to implement a method and I was supposed to describe an issue with each solution.

About a week later I got a call with an offer. Everyone I talked to was really friendly. They seem like a really great group of people to work with.

Interview Question – Given a byte, rearrange the bits so that bit0 gets swapped with bit7, bit1 gets swapped with bit6, etc.   View Answer
