I applied through other source. The process took 1 day. I interviewed at Qualcomm (Hyderābād) in Jul 2022
Interview
First round was about testing problem solving skills.It is important to know Data structures and algorithms basic knowledge and strong Problem Solving skills. You are Given a random problem and asked to solve , you need to tell ur approch (could be basic and brute force) and try to improve it.with that exercise you will assessed on problem solving skills try to solve atleast 100 problems ( don't code ) just think and come up with an approch and try to improve it and then u will be able to clear this interview.For example look at water container problem from leet code, it was one of the questions asked to me.Next rounds will be testing deep learning and Machine Learning fundamentals.
Interview questions [1]
Question 1
Basic Problems from Leetcode , geeks for geeks like water container problem, deleting an element from the end , finding a duplicate number from an array with all distinctive elements except for one.
I applied online. The process took 3 weeks. I interviewed at Qualcomm (Seoul) in Oct 2025
Interview
I applied online. The first round is an online technical assessment on computer science & machine learning basics. Once passed, there is another technical interview via Zoom, with a focus on deep learning & coding.
To be fair it wasn't particularly difficult, but I wasn't well prepared and there's a little bit of language barrier (korean & english), so I didn't get an offer in the end.
->One easy and one medium leetcode level problem
->CNN based number of parameters calculation
->About project , what dataset was used ,what model was used
->C++ class based questions , design a simple class
->Filter related questions
