I was interviewed on-campus at IIIT Jabalpur for Engineer role at Qualcomm
Interview Process
Test Technical Interview HR Interview
Round 1

Test

Duration
60 Minutes
No. of Questions
50 questions
Test Sections
  • Section 1: Quantitative Ability (20)
  • Section 2: Quantitative Ability (20)
  • Section 3: Programming Skills (10)
Interview Experience
The Quant and Programming sections were long but fairly easy; I pretty much sailed through them. However, the core EC section was really lengthy and not so easy, and also had negative marking. I was able to complete the first 2 sections completely, and around 11/20 questions in the core section.
The Quant section touched basic topics like probability, algebra and simple geometry. Programming questions were quite syntax-based, rather than algorithm-based. In the core section, the focus was on device physics and digital electronics, including combinational/sequential circuits and microprocessors.
Interview Tips
1. Practice Quantitative sections. A LOT. Speed is of the essence in these sections, because almost everyone is on the same level as you are where mathematics is concerned.
2. Know the basic syntax of C++, that is the most common language you're tested on in the Programming section. Also know simple data structures and complexity calculations.
3. The core section is the most important one, so make sure your knowledge is sound and practice solving digital circuits as fast as you can.
4. The EC section is generally quite lengthy, so quickly flip through the questions once and then figure out what questions you can do for sure, finish those and then start on the remaining ones. DO NOT STAY ON ONE QUESTION FOR TOO LONG, because you won't even be able to haphazardly guess on the other questions because of the negative marking.
Round 2

Technical Interview

Interview Questions
  • Question 1: Explain the difference between Moore and Mealy state models.
  • Question 2: Explain the difference between Moore and Mealy state models.
  • Question 3: Draw the state diagram and the clocked D-flipflop circuit for a 0110 sequence detector.
  • Question 4: What is parity and how is it used? Draw the circuit diagram for a parity checker.
  • Question 5: Design a memory organization given the size and block units.
  • Question 6: Draw the circuit diagram for a random number generator.
  • Question 7: What is a Schmitt trigger/inverter?
  • Question 8: Arrange the inputs to AND gates so that power usage is optimized/delay is optimized.
  • Question 9: Draw the CMOS circuit for a given logic equation and do the corresponding W/L sizing.
  • Question 10: Draw a circuit for a set of logic equations using PLA.
  • Question 11: Draw and talk about a basic SRAM cell.
  • Question 12: Given the delays for gates and wires, draw output waveforms for the given logic circuit.
  • Question 13: What is Min-Cut placement algorithm? Given some block sizes, use the algorithm to place them on a given chip area.
  • Question 14: Given a clock waveform of frequency f, design a circuit to get an output of frequency f/3.
Interview Experience
I had only one round of technical interview. The interviewer was a person who'd worked at Qualcomm for around 5 years, as a Senior Engineer. The questions were not too tough, but challenging enough that you had to be quick at circuit evaluations. I wasn't able to solve all the questions completely, but talking aloud really helped, the interviewer himself would pass on hints or correct me sometimes if I went too far off on a tangent.
All in all, the interview lasted for about 45 minutes and was tiring but really fun if you like EC. For the first time, I realized that I actually knew electronics after studying it for 4 years! ;)
Interview Tips
1. Many people must have said this to you, but I'll say it again: Don't be too nervous. The questions are asked in such a way that you will definitely not be able to do all of them, so don't freak if you miss something here and there, they know it too!
2. Make sure you have the basics of logic gates, sequential design and digital VLSI circuits down pat when you're preparing for the interview. These are the main areas they are looking for in the VLSI Electronics interviews. Apart from these, a knowledge of Computer Architecture and basic VLSI CAD wouldnn't hurt!
3. I can't emphasize this enough: Talk out when thinking. It is very important for the interviewers to know what kind of technical logic you use when working out problems, and most often they start talking with you, which leads to an insightful discussion rather than a Q&A session.
4. Make sure your interest in the field also comes across; as far as I saw, they're looking for people who actually like EC and will be able to work hours together without getting bored of it (Well, not too much :P)
Round 3

HR Interview

Interview Questions
  • Question 1: Explain a little about your M.Tech. project.
  • Question 2: What do you know about Qualcomm?
  • Question 3: Have you ever worked in groups? What kind of work was it?
Interview Experience
The HR interview wasn't really an interview; it was more of a 15-minute discussion with an HR person. He was basically looking to see whather I would be able to fit into a team-oriented work environment and add something to it, that's all. Apart from that, there was mostly a discussion on the package breakdown, and the kind of work and teams we could be involved with in Qualcomm.
Interview Tips
1. Know something about Qualcomm, so that you're able to answer the first question they'll mostly ask.
2. This round is set to get to know you, so clear all your doubts and ask as many questions as you want.
3. Once again, try to express your interest in working in the field of electronics; if your passion shows, this round is pretty much cleared!

Motivation for applying
I've always been interested in Electronics, ever since I studied the 8085 Microprocessor in the 12th Grade. Even when I joined IITKGP, I changed my Department to Electronics after my first year, because that's what I wanted to study!<br />
Circuit design is one of the most interesting and challenging fields in today's electronics field, and I would love to see what happens, and be a part of it. Especially since right now we're on the verge of a big change - we're close to moving away from silicon-based designs; what happens next?

The first two sections were relatively easy. Section 1 had some probability and comprehension style questions. Section 2 had questions on C programming, Computer architecture, and data structures. Manage your time properly. Don't get stuck on a question for too long. Revise C syntax and precedence of operators for the basic programming section. The communication section was relatively tougher. It required knowledge of modulation schemes(QAM, BPSK, MSK and so on), Digital signal processing.
Interview Tips
Manage your time properly. Don't get stuck on a question for too long. Revise C syntax and precedence of operators for the basic programming section. If you have not done a course on communication systems opt for the electronics or software test.
