3 technical rounds first one was to implement BST from scratch but in multiple stages. like those in codesignals without any autocomplete. 2nd round was also related to BST where you need to find rightmost left node. i dont remember third one.

The interviewing was quite smooth but the interview process, where we try to reach out to the HR for future communications was a hassle. I had to reach out for at least 2 weeks before I was presented with the next steps, and apparently the interviewing progress was also not updated. Apart from that I enjoyed meeting the team and discussing mutual goals.

Applied online through their website. Was contacted after more than 1 month (reasonable for a company this big). 1) First phone interview with a senior engineer. Everything went smooth, we had a good chat about the position and the roles. 2) Second phone interview with another engineer from a different team. Again everything went smooth. 3) On-site interview. Met the team in Europe and had a nice chat with them. Everyone was friendly. The overall process was very smooth and very well handed by HR. Overall a very pleasing job interview experience. All questions were deeply technical and related to my position, no whiteboard coding, quizz, complex (and mostly useless) algorithm questions or other useless stuff like this. I always appreciate a job interview where they try to actively assess your skills, and not how much you remember from your university degree. I hope more and more companies follow this. Thanks Qualcomm. Received a very good offer, but I did not accept because I had another one which was more on track with my aspirations as an engineer vs researcher.
