Candidate interview experiences
First-hand accounts from people who interviewed at Qualcomm.
Hardware Engineer
The interview process was smooth and professional. It started with a short phone screening, then I had two technical interviews. The interviewers were friendly and focused on fundamental hardware concepts, problem-solving, and basic circuit analysis. They also asked about my previous project experience and some situational questions related to teamwork and deadlines.
- Can you tell me about the most popular MOSFETs in the industry and provide basics regarding digital circuits?
- Can you tell me about your previous project experience and some situational questions related to teamwork and deadlines?
Hardware Engineer
So, Qualcomm visited our campus for 3 hardware roles, I interviewed for the SOC verification role. First was an online assessment with negative marking. It had 3 sections: Aptitude (easy to moderate, 30 mins, 20 Qs), C programming (moderate, 30 mins, 20 Qs), and Digital (moderate to hard, 30 mins, 20 Qs). Then there were technical rounds. Round 1 was about 20 mins, where they asked for my introduction, discussed my projects, explained the role, and asked about my career plans for 5 years and why I'm interested in Qualcomm. They also threw in some C programming questions about arrays and algorithms. Round 2 was about 40 mins, focusing more on technical concepts like ring oscillators, setup/hold times, STA, binary search, op-amp circuits, clock concepts (skew, jitter), synchronizers, cache memory (lines, dirty bits), watchdog timers, SRAM vs DRAM, and Verilog. There were also two aptitude questions about gates and a cube. Finally, there was an HR round, which was short (5-10 mins), asking about me, my skills, hobbies, family, strengths, and preferred location.
- Could you tell us about yourself?
- Can you discuss your projects in detail?
- Why are you interested in Qualcomm?
Hardware Engineer Intern
I applied for a hardware engineer internship and got selected. The interview process started with the interviewer trying to make me comfortable for the first 5 minutes. Then, they asked me some simple questions about signals. About 10 minutes into the interview, I was presented with a coding problem concerning a window-based issue. Finally, the interviewer inquired about the functionality of flip-flops.
- Tell me about signals.
- Could you solve this coding problem: finding the minimum of the maximum of elements within a k-length subarray?
- How do flip-flops work?
Qualcomm Hardware Engineer Interview Questions
Quoted word for word from Qualcomm interview reports.
“Regarding switched capacitor circuits, what effect does adding a series resistor to the input voltage source have on the gain, and what is the reason for this effect?”
Read reports →“What would happen if the body terminal isn't shorted to the source? What if it's connected to a higher voltage than the source?”
Read reports →“Given a circuit and delays, calculate the setup and hold time required for it to function correctly.”
Read reports →“Regarding a one cycle or multi cycle path between two flops, how does the target flop receive a glitch?”
Read reports →“Using FSM in Verilog, how would you implement a detector for the sequence 10101?”
Read report →“For the cube room riddle: What is the shortest path for an ant to travel from one corner to the diagonally opposite corner of a cube with side length 'a'?”
Read report →“Describe how to create a summing circuit using an op-amp. What would happen if we swapped the inverting and non-inverting inputs?”
Read report →“You have 7 bags of coins, one with coins weighing 1.1gm and the other 6 with coins weighing 1gm. With a weighing machine and only one weighing, how do you find the bag with the heavier coins?”
Read report →“If two flip-flops share the same clock signal, will the clock reach them simultaneously? If not, explain why and suggest a way to mitigate this.”
