Staff Verification Engineer Interview (Positive Experience; Difficult Interview)
I applied online and the process took 3 months - interviewed at Qualcomm in February 2014.
Interview Details – Applied through the Qualcomm Career section in Sept and did not get any communication for more than 2 months. Out of the blue got a call from HR wanting to schedule a Phone Screen, and within a couple of day I was Phone screened. Phone screen was really stimulating, lots of questions regarding ASIC verification, Memory Management, Cache Coherency and FPGA based emulation, Palladium/Veloce emulation flow and using emulation for Simulation Acceleration. It was a nice 2 way discussion which made it real fun, lasted about 45 minutes. Told next day, they wanted to setup an onsite, but since it was around X'mas, we were not able to schedule the interview till early Jan. The team was very flexible in terms of interviewing as I fell sick and had a planned vacation, due to which I wasnt able to interview till mid-Feb.
The Onsite was short in duration but concentrated in content. Welcomed by my manager and was taken to a conference room, where I had 2 1 hour group interviews with 4 people each. 1st hour was related to my resume and emulation experience more relevant to my role and the 2nd hour was general ASIC verification questions with a team of 4 sr Staff level engineers. Got an offer a week later, but due to a relocation, working out the logistics took almost another month before I could join. Very slow process overall. There were 2 stages of reference checks, first after the phone screen and 2nd after the onsite, before the offer was made. There was no HR or personality interview, only technical interviews.
Interview Question – Questions regarding STA mode and Transactor based Simulation Acceleration:
How would you implement a transactor? Use SystemC or System Verilog and why? How will you communicate between the DUT and the transactor testbench? Explain the PCIe speedbridge interface and how would you debug it? Answer Question
Negotiation Details – A couple of rounds of negotiation and I was able to get the desired package, though, there was some flexibility in terms of the benefits.
Software Engineer Intern Interview (Positive Experience; Average Interview)
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.
Interview Question – Reverse a linked list Answer Question
Senior Digital Design Engineer Interview (Negative Experience; Average Interview)
I applied online and the process took 2 weeks - interviewed at Qualcomm in February 2014.
Interview Details – Applied online then contacted by email for phone interview. During call interviewer was very arrogant with poor english but good technical skills. I confused because of his speaking and mess up with very basic techical questions. At the end he asked if I have questions and after I asked he refused to answer (my questions was not related to confidential information). Advice to hiring managers - please choose nice people as an interviewer, this is first impression about your company. I am not going to personally apply for any more positions or to suggest somebody else.

2- What is channel coherence time and bandwidth
3- How to perform maximum likelihood detection of QAM over AWGN and fading channel
4- Questions on detection of MIMO-OFDM? Difference between MMSE and MLE? which one is better? and which one is optimum? How they perform In high SNR and low SNR?
5- Questions on fixed-point implementation

Embedded Software Engineer Interview (Negative Experience; Average Interview)
I applied online and the process took 3 weeks - interviewed at Qualcomm in August 2013.
Interview Details – After the telephonic interview, I was asked for an on-site interview. The on-site interview had 7 back to back interviews. All the interviews are in different building locations and that was the biggest challenge. Some interviewers were late or were missing from their offices, so the interviews time had to be extended. I had no breather in-between those interviews as I had to literally run to catch up the other interviews on time. Overall a very bad experience.
Interview Question – Find a software bug from a code snippet. The code had something to do with malloc and calloc. Answer Question
Web Software Engineer Interview (Positive Experience; Average Interview)
I applied online and the process took 4+ weeks - interviewed at Qualcomm.
Interview Details – My first interview was a technical phone screen for 30 mins with overall questions on my resume. After that I was selected for onsite in SD and had a whole day 5 hrs interview with all team members on 1:1 basis.
I had pretty good interview but unfortunately the main person who supposed to be a decision maker and boss of all the team members was missing in interview panel. I didnt got the offer and asked the HR for reason for not getting selected and her response was you did good but we dont have policy to share the interview feedback. I am still not able to find the reason of not having an offer.
Interview Question – All the questions were relevant to my technical skill set. Answer Question
Engineer Interview (Positive Experience; Average Interview)
I applied online and the process took 2 months - interviewed at Qualcomm.
Interview Details – I interviewed with 6 people; one of them took me out to lunch. Each interview was 45 minutes to an hour long. Interesting questions and great people. HR was bad - it took a very long time to hear back from them. I had other offers in hand so I had to continually reach out to them for feedback. They got back to me at the last minute with an offer. When I started the job, I was informed that I had been placed in a different role than the one I had interviewed for - I was not consulted on this change in role. I thought that this was very unprofessional.
Interview Question – A question about flip-flops - I was interviewing for an analog position so this was unexpected but I worked through the problem. Answer Question
Negotiation Details – No negotiation allowed for a fresh graduate is what I was told. When I joined, I found out that this was not true and that I was very underpaid.
