Qualcomm Software Development Engineer SDE interview questions

Applied offline, got call from recruiter. First round was QA -> Technical Round Solved the problem using C++, as it was my primary language. But they insisted to solve it in python. At that time python librarians was not to easy to me. I've explain python libraries can be learned, still he insisted to solve it in python all although the the job description was C++/ Python. And as usual rejected.
