Full Details
The company visited our campus for 3 hardware roles, physical design role, SOC verification role and FPGA design role. I was interviewed by the SOC verification team.
Round 0 Online Assessment(with negative marking) > Section A -> Aptitude - 30 mins, 20 Questions -> easy to moderate level > Section B -> C programming - 30 mins, 20 Questions -> moderate level > Section C -> Digital - 30 mins, 20 Questions -> moderate to hard level.
Round 1 20 mins approx > Asked to introduce myself > Discussion on my projects > Told about the role they came for and asked me if I am okay with that role. > Why Qualcomm and where do I see myself or what are my career plans for the next 5 years. > Asked array based C programming questions like, merge sort algo, finding second largest element in a array, time complexity.
Round 2 40 mins approx > Discussed about the role > Ring oscillator > Setup time and hold time > What is STA > Binary search algo, pseudo code and time complexity > Negative feedback opamp > Summing circuit using opamp and what happens if we interchange the inverting and non inverting terminals > Suppose there are 2 FFs having same clock, then will clock reach exactly at the same time. If not why and how it can be reduced. > clock skew, clock uncertainty and clock jitter. > 2-FF synchroniser > What are cache lines > What are dirty lines and dirty bit > What is a watch dog timer > what is Cache memory, what is its need and importance. > difference b/w SRAM and DRAM. > Why SRAM is used in Cache > Verilog code for AND gate using MUX > Is Stack LIFO or FIFO > Is SRAM volatile or non-volatile, why ? > Aptitude question 1: There are 100 gates and 100 people, all the gates are initially closed, the 1st person will flip the 1st, 2nd, 3rd, ... till 100th gate. 2nd person will flip the 2nd, 4th, 6th, .. 100th gate, 3rd person will flip 3rd, 6th, 9th, ... 99th gate, and so on till 100th person. After all 100 people do this, how many gates will be open ? (flip -> close if open and open if close) Answer: floor(sqrt(N)), where N = total no. of people. The logic is that the rth gate will be open at the end if r is a perfect square. > Aptitude question 2: In a cube shaped room with side 'a', there is an ant at one of the corner, it can't fly obviously and it can move on the floor, the walls, etc. So what is the minimum distance it has to travel so as to reach the diagonally opposite corner of the cube. Answer: sqrt(5)*a Hint given: open up the cube into a 2D plane, then you can see the shortest path
HR round 5-10 mins > Asked about myself, my skills, hobbies, family, strengths. > Preferred job location.

About Qualcomm Interview Reports
This question was reported by a candidate who interviewed at Qualcomm. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Qualcomm are the higher-signal extractions to take from this report.
For broader preparation context, the Qualcomm interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Qualcomm reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Qualcomm Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Qualcomm reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
