I applied online. The process took 2 months. I interviewed at Dexcom (San Diego, CA) in Oct 2015
Interview
First Phone call (1 hour) with 3 people. It was a very basic behavioral interview. They asked about my previous projects and skill sets. Not much technical. Then i got a call for onsite interview after almost 2 months. Onsite interview was 3 hrs or so , with 4 people, one on one. It wasn't that hard.
