Difficult Interview

Application

I applied online. The process took 1 day. I interviewed at Qualcomm (California City, CA) in April 2009.

Interview

I had a technical telephonic interview which lasted for about 45 minutes. I had applied online on their website and got a call in 2 weeks time to schedule for a telephonic interview.

I prepared lotta basic C interview questions and fundamentals of OS. I should have done more preparation regarding some of the projects that I worked on as I was not very confident in the way I explained to him some of the OS fundamentals that was used in some of my relevant projects.
