    Interview Questions

    • First interviewer did bus connection verification. so he asked about the protocol of ahb and axi. Then he asked how many vip should be used for their verification environment. I didn't understand the question clearly. Because if we want to keep CPU and the code run on real CPU, we don't need to replace these interfaces with VIPs, but if the CPU needs to be replaced, only other slave/master interfaces need to be replaced by VIPs. After he cleared it, what he wanted to do was to replace all the CPU interfaces and other IP interfaces. The second interviewer asked 2 questions: 1) how to check the module was reset by reading/writing registers? The premise for this was there was no spec for register. 2) how to check an interrupt was generated? There was a bit in the register for the interrupt signal. The third interviewer asked the following questions: 1) virtual memory structure 2) spin lock 3) tomasulo 4) fibonacci generator The last technical interviewer asked: 1) shell questions: search a key word in a file and count how many lines contain the key word 2) Perl sort question: user perl to sort a hash with key or with value 3) set environment variable in Perl 4) fibonacci generator 5) there are 2 buckets: 5 litters and 3 litters, how to get 4 litters of water 6) there is a rectangle pie, remove a small rectangle in that large rectangle, after that, use a straight line to cut the pie to get 2 equal areas. There was another question I forgot who asked: use SystemVerilog to generate address with the following constraint: 0x0 (mem1), 0x4(mem2), 0x8(mem3), 0xC(mem1), 0x10(mem2), 0x14(mem3) ...   4 Answers

    I applied through a recruiter – interviewed at Qualcomm.

    Interview

    I had a telephone interview with the PHY verification manager. He was very rude. Called me 12 mins late and never mentioned about it. No sorry nothing. He was in a hurry from the begining. Asked me if I know DSP. That was his first question. I have not mentioned DSP any where in my resume. Then after 10 more mins of conversation he said HR would get back to me. Personally I would not like to work work under such a manager.

    Difficult Interview

    Application

    I applied online. The process took 3+ monthsinterviewed at Qualcomm (Raleigh, NC) in February 2014.

    Interview

    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 Questions

    • 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

    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.
