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.
