I applied online. The process took 1 day. I interviewed at Qualcomm (Bengaluru) in Jan 2016
Interview
There was 8 rounds of interview. Mostly questions about the information theory, signal process and few analytical questions. The whole process took one day . It was exhausting. I cracked every question. They never closed on the interview, I did very well. But it appears like these fellows are all from IISc and want to hire only from there brethern.
Applied online and then received interviews. First round with ML basics. If passing the first round, then go to the onsite interviews for a whole day, including maths, coding, ML basics, research talk, hiring manager interview.
Interview questions [1]
Question 1
Asking a lot of maths including calculus, linear algebra, and probability. In ML basics interview, asking optimizers, overfitting, bias-variance trade-off. Coding interview is much easier, just leetcode medium.
