I applied online. The process took 1 day. I interviewed at Qualcomm (Bengaluru)
Interview
The role was for machine learning engineer. The HR called just the day before evening and asked to come early morning the next day for interview. Not a single question was asked from my resume or related to machine learning/data science. There were two rounds which took more than 2.5 hrs and the questions were only on c++. They didn't even accept the pseudo code /logic. Main focus was on C, c++ syntax their features different types of memories. When I mentioned I haven't put c, c++ in my resume and I am not proficient the response received was we need ml engineers who are proficient in C. Atleast they should see the resume before shortlisting, the list of skills listed in resume. Such a waste of time and disappointment!

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
