    I applied online. The process took 3 weeksinterviewed at Qualcomm.

    Interview Details

    two onsite interviews plus three phone interviews, a little repetitive but it was good to get access to lots of different people to ask them questions. Had to speak with people in the US so those interviews were in the evening but that was fine. covered my general background, industry knowledge, most difficult hires, dealing with line managers,strengths, weaknesses

    Senior DSP Software Engineer Interview

    Anonymous Interview Candidate in Farnborough, Hampshire, South East England, England
    Anonymous Interview Candidate in Farnborough, Hampshire, South East England, England
    Application Details

    I applied online. The process took 3+ monthsinterviewed at Qualcomm in November 2009.

    Interview Details

    Applied online, called on phone interview within 2 weeks. The phone interview was from my would be manager who said the interview would take 30 minutes. Instead, we talked for 1 hour, 20 minutes.

    Two weks later I get notice from some person at Qualcomm to tell me I need to have two more phone interviews with people in SAN DIEGO. WTF? I mean the job is in the UK so why do tech people in San Diego need to talk to me?

    Anyway, talk to people in San Diego. First person calls a bit late, interview runs 45 mins instead of the allotted 30, which makes me late for the next call, and the next interviewer huffily blames the lateness on me. Both San Diego interviews were technical but amounted to mostly me explaining how to multiply two fixed point numbers and minor uninteresting C specific type questions. Nothing is said about the actual job..

    Invited to onsite interview in the UK.
    The in person interview was very technical with details not very relevant to the position. They asked me again how to multiply floating point numbers. You'd think that they'd know how to look it up by now! Then they asked me "what's a Q15 representation?" all questions that were rather too specific and irrelevant to a comms DSP position. Then I got a written test, with questions involving deciphering what a piece of code was doing. The piece of code was computing x raised to the power n but it was programmed in a very weird, obfuscated, inneficient way involving taking modulo of n to determine whether n was odd or even, etc (lots of unnecessary steps) that made me worry that that was the way they actually wrote code at Qualcomm. They also asked me what is j raised to the power j and when I answered "It is sqrt(minus one) raised to the sqrt(minus one) " they didn't like the answer.

    They did not describe to me what the job entailed, nor gave me time to ask questions or look much at the real work they were doing other than a very cursory, superficial "lab tour".

    Two weeks later, they said "they wanted to move forward with the offer".

    Then silence. Two weeks after that I wrote to ask what was going on. They claimed they wanted to discuss the offer by phone. I asked "what offer since you haven't sent me one". They were adamant on only discussing things verbally, nothing was ever written.

    After a month I finally got an informal "offer" by email, detailing salary, but being nonspecific on other benefits including stock option price and vesting period and bonuses, thus giving me no real way to seriously evaluate the offer due to lack of details.

    Reasons for Declining

    Compensation level was too low. Interviewers seemed too concerned with irrelevant, obscure details of implementation as opposed to big picture, important fundamentals and DSP and communications theory. Incompetent HR also made me wary of ever working there. But especially compensation offered was WAY too low for such a supposedly successful "top 100 companies to work for" company.

    I applied online. The process took a dayinterviewed at Qualcomm in January 2007.

    Interview Details

    After applying I received a reply in one week for on site interview.
    Overall the interview was pretty much technical. Questions ranged from regarding university project till the actual communication theory. I will advise to study your communications related modules properly before the interview.
    Also the background of the company is important but I think it depends on whom is interviewing. I was interviewed by only engineers and hence wasn't really asked as much house keeping questions as I would had normally been.

    Application Details

    I applied online. The process took 4 weeksinterviewed at Qualcomm.

    Interview Details

    I applied online through Qualcomm's website. The recruiter first contacted me about 2 weeks after I applied, and my interview was scheduled for the following week.

    The interview process was very friendly and conducted very efficiently. It consisted of two phone interviews, one HR interview and one technical interview. The HR interview was you very standard interview - i.e. Why Qualcomm? Why Computer Science? etc. The technical interview was also very standard, consisting of one coding problem, two brain teasers, and two conceptual questions.

    After 2 weeks or so, I got a verbal offer over the phone, and a week later received the formal offer letter.

    Staff Hardware Engineer Yield Interview

    Application Details

    I applied through an employee referral – interviewed at Qualcomm.

    Interview Details

    Applied through referral, called for on-site interview.
    Total - 8 rounds , Overall NONE of the interviewer is prepared, NONE of them are on-time.
    HR was the first one to interview me, she came after 10 mins of scheduled time and asked my present salary, other benefits and relocation etc. hardly 10 mins talk and then gave me a list of interviewer and schedules. Then she came to lobby and gave another list with some adjustments in schedules.
    I was waiting in the lobby for another 35 mins, first technical interviewer came (15 mins late) and took me to his office, he told that "I don't know why the hiring manager asked to interview you anyway tell me about yourself" and 30mins of white board interview.
    He dropped me in the lobby then next interviewer came 20 mins late, then the same set of questions, and took me to lunch in the cafeteria for lunch.
    Headed to another building, Third was the most important person, "Hiring manager", he came late by 10 mins and talked to me for a 5 mins then told me that he got another very important appointment so he rescheduled my interview to end of the day.
    Waiting in the lobby for another 40 mins.

    Fourth person is somewhat OK, because he is NOT very late and then he asked for a resume from me. Same set of questions from "tell me about yourself to work experience etc."

    Back to lobby, next person came to lobby 10 mins late. He told that he is late because he tried to print my resume, then he asked some very basics from electronics engineering, i did not do well on this round because i did not revise the basic circuit theory. He looked to be very disappointed nad asked me "what do you know in electronics?" and that round ends somehow,

    He took me to the next interviewer's office, we were waiting in his office 10 mins, the interviewer came and looked to be shocked by seeing us in his office, He started asking some basic physics laws, i don't know if we use it anywhere in the Yield engineer job, managed to give some reasonable explanation.
    Back to lobby, wait there for another 1 hr, receptionist told me that the interview round cancelled as the next person is OUT due to some urgent work.The hiring manager asked me to wait for hte hiring manager.
    The hiring manager came back to me after office hour, took me to a conference room and he explained the job roles and responsibilities, team hierarchy etc. then some questions about my work experience and the paper i published recently etc. Finally he asked the usual question, "Do you have any question?" I took this time to ask him, I was completely gone mad by previous interviewer time management and questions. I asked him that, do we need to use any physics law in job? is there any problem with watches in QUALCOMM because NO one is ON time. He simply smiled and said "we are very busy, you know how busy we are in meetings bla bla"
    Then he told he will email me within 2 weeks. It's already 3 weeks, i sent a reminder as formality, he replied with the same sentences what he told me in the interview. Should i expect anything more from this team

    Interview Details

    I sent in my resume. A few weeks later they got back to me telling me they would like to interview me. The interviews tested my knowledge of how C++ worked but, even though they were all coding questions, mostly tested my ability to think. I had a competing offer at the time with a strict time limit and they did a good job of getting back to me before my other offer expired.
