Engineering Interview

I applied through an employee referral and the process took 4+ weeks - interviewed at Qualcomm CDMA.

Interview Details – It is difficult to break into the hiring process at Qualcomm because so many people apply. The best ways to improve your chance of getting hired: try to get an internship while you are still in college. They offer many opportunities for engineering interns, and the experience will help you no matter where you go after college. If not a new grad, be sure the key words in your resume are the right kind for the job you want. Prepare extremely well for the interview process. You will likely talk to 6 to 8 people, and will likely be called back for another round before being hired. Because it is a large company with many positions hiring, the process is cumbersome and can take far longer than you think it should. Do your best to get business cards or at least the full names of the people who speak with you. Send thank you notes after the interview, by paper or email, and it is OK to inquire a week or two later to the HR representative about how the process is going. You can also ask where they are in the process while you are interviewing. You will interview with people from more than one department, and will get technical questions and experience/personality questions. If you are an electrical engineer, you should be able to describe basic circuits, and may get some very in depth questions, so brush up on what you should know as an engineer in your field! Learn something about Qualcomm technology so that you can ask good questions. Any engineering interviewee will get some technical probing. Know as much as possible about what Qualcomm does, how CDMA works, what kinds of technologies are used to make Qualcomm products and where Qualcomm products are used. If you have some work experience already, emphasize what you have accomplished and what your role was in different projects at your current or previous jobs. You want to sound like someone who can be cooperative, creative, hard-working, take initiative, have good judgement, solve problems, keep company goals in mind, etc. Think about how to describe how you have done these things in detail before you go for the interview. Some people at Qualcomm are very detailed interviewers with lots of interviewing experience, so expect it and be prepared. You will not likely be given a personality test, drug test, or IQ test of any kind.

Interview Question – Most difficult questions will be probing of previous experiences and where you have shown leadership. This is a company that wants to hire leaders at every level. Know what you will say when asked what your areas of least and greatest strength are. The best type of weakness or least strength can be something that is actually a strength, it depends how you word it :) For example, "I don't have patience sometimes when people say they will do something and then they don't do it." Your are saying impatience is a weakness, but really you are showing that you are the type of person who does what he says he will do and expects the same from others.   Answer Question

Negotiation Details – Not a huge amount of negotiation possible, but a few thousand can be gotten.

Interview Details – Applied through a reference at QCT. First round was a phone interview which was mostly C with couple of OS related questions. Was called for an on-site interview.
