I applied online. The process took 1 day. I interviewed at Qualcomm (Hyderābād) in Apr 2007
Interview
My Interview consisted of technical discussions with 5 different individuals 1:1.
It is a thoroughly technical interview in which following things are asked/evaluated - DSP(Digital Signal PRocessing) fundamentals, DSP Assembly language programming skills, C programming skills.
Questions which i remember now roughly -
DSP - Digital filters(IIT,FIR), their applications, design of filters, DSP algorithms like autocorrelation, convolution, DFT,FFT.
Assembly language programming - Solve simple problems(square root, cube, reciprocal) using only certain assemlby language mnemonic instructions(not all instructions are given to be avaiable)
C programming - Whats error in the code. whats the output of code,etc. Write code to solve some problems, factorial, etc.
Interview questions [1]
Question 1
Can u write a sqaure root algorithm in DSP assembly language as efficiently(MIPS wise) as possible.
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.

Sorting & searching algos, Hard leetcode, resume deep dive
I got the referral from employee and my resume shortlisted. There is a hacker rank test and followed by three interviews and hr discussion.
Process was smooth and all my interviews are done in one day.
