I applied through an employee referral. The process took 2 weeks. I interviewed at Qualcomm (San Diego, CA) in Jul 2019
Interview
Telephonic round - Few bit manipulation questions, one or two coding questions and few standard OS concept questions along with few questions based on your resume
Onsite- 4 rounds of interview each spanning 45 mins(out of which one person may extend his/her interview to lunch)
Interview questions [1]
Question 1
Coding questions:
1. Bit manipulations - Count number of set bits, set a particular bit or clear a particular bit, find if a number is a power of two...
2. String manipulations - Different ways of string transformations , Removal of few letters from an array, substring matching
3.linked list - Given two linked lists with each list containing digits, find the sum of the digits and place the result in a new list with nodes holding digits of the sum. Arrays vs linked list...
4. Binary trees - Write code to print the BFS traversal
It was a 5-step interview. Four of them were technical and the last one was with HR. The first two interviews were conducted with the Ireland team. The interviewers were great guys. They checked my basic C language and software design knowledge in those interviews. The last two interviews were conducted with US-based engineering managers. They asked both behavioral and technical questions, as well as a coding question in the last part of the interview. I suggest doing some practice on LeetCode before taking the interviews.

Question 1
Design a task scheduler on the bare metal environment.
It is first round with HM. HM digging deep on my resume bullets. HM mainly asked behavioral questions for each bullets. Overall experience is great. We had great conversations. one pseudo coding on parallel programming.
I applied online. The process took 3 weeks. I interviewed at Qualcomm (Noida) in Dec 2025
Interview
They gave no idea about overall process. Just calling to scheduling rounds. No alignment discussions. Just kept on taking technical rounds without sharing any details of role. And post all rounds gave an offer way below my current compensation. Overall wasted my time & I would recommended anyone in my network to go with them.
4 technical rounds were there. Mostly general - DSA, sorting & searching algos, some hard leetcode, system design & resume deep dive.
