28 interviews found
I was interviewed in Sep 2017.
5 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: Each section had 20 multiple choice questions and each section was allotted 30 minutes. The aptitude section was fairly difficult due to time constraints. The other two sections had several questions with unfamiliar concepts; however the other questions were easy.
Tips: Practice aptitude questions to increase speed in problem-solving.
Duration: 1 hour 30 minutes
Total Questions: 60
Round: Technical Interview
Experience: The first round was fairly short. The interviewer asked only three questions and I was able to answer all except for the overlap-add question. However I had the intuition to get to part of the answer.
Tips: Just brush up concepts in analog communications and DSP.
Round: Technical Interview
Experience: The second round was longer. The interviewer asked questions mostly in DSP and analog communications. I was able to answer all but one, which involved interpolation in discrete-time domain. The interviewer gave hints on how to get to the solution of the bit-rate and the interpolation question but I was able to answer only the former. The interviewer also asked if I did a course on Linear Algebra, and I affirmed it but I had no memory of it.
Tips: Just like in the first round, but expect more difficult questions.
Round: HR Interview
Experience: The HR interview was very short and the interviewer did not ask any of the typical HR questions except for if I were offered an internship in Communications, I would take it.
Tips: If you make it this far, you'll most likely make it. There is no need to prepare anything in advance.

Interview Preparation Tips
Round: Test
Experience: The questions on aptitude were based on quantitative and logical reasoning. Questions were simple but you should have a good speed. In the programming section there were find the outout kind of questions and some theory questions based on virtual functions and abstract classes.
In technical questions we had to choose from hardware software or communication. I wrote the test for communications. Questions were based on different modulation techniques like qpsk, msk and also based on dsp. Some questions were about coding techniques as well.
Duration: 1 hour 30 minutes
Total Questions: 60
Round: Technical Interview
Experience: The overall experience was really good. The interviewers were frirndly and were helping out in case you get stuck. They want to see how clearly you know your basics.

4 Interview Rounds
Interview Preparation Tips
Round: Test
Experience: Aptitude and programming questions were easy but needed speed and accuracy. Technical round had questions from the profile we selected (hardware or communication or software). I chose hardware which had questions from digital electronics and solid state devices. Third section had lengthy questions but less time. So attempting perfectly the questions you know is better than spending time on all the questions without fully solving.
Tips: Technical round was tough given the time constraint. So be well prepared for it
Duration: 90 minutes
Total Questions: 60
Round: Technical Interview
Experience: Basic questions from digital circuits like working of flipflops,FSM design, mux from logic gates, counters and frequency dividers etc.
Also questions about my project mentioned in resume. After that a little chat about the kind of work and the projects there.
Tips: Be clear with the basic concepts of the subject. Be confident and don’t feel nervous while answering. Write a genuine project in your resume as they may ask you everything about the project.
Round: HR Interview
Experience: Asked to summarize my resume. A small conversation about my interests. I was asked how I came to know about Qualcomm. Then they asked if I had any doubts and later informed me that I was selected. It was a very friendly interaction.
Tips: Knowing a little bit about Qualcomm may help.
