    I applied online. The process took 2+ months. I interviewed at Qualcomm in April 2017.

    Interview

    I applied through their career website, got a response within a week for a phone interview. Phone interview was a lot focused on my resume, about the project​ and technologies I worked with. Within 10 days I got an on-site interview invitation. I interviewed with 6 different people, 3 engineers, 2 manager and 1 HR. I prepared using Glassdoor and studied over things mentioned in requirements. It was really good experience, everyone was really cool and that helped me to not freaking out as I'm usually nervous.
