Originally applied online for the full-time research position, and quickly got a reply. During the initial phone screening, I showed interested in internship instead since I was still waiting for graduate school results. The recruiter told me she'd send my resume to the intern recruiter. After waiting for 1 month, I got a surprising contact from the intern recruiter. I then had a 3 hours, 3 people back-to-back phone interview with two research engineers and the director or research (pretty cool!). The questions were not very technical in nature, but more towards critical thinking. I am an EE and did not get an actual circuit question. I think the fact that I played around with many DIY projects involving wearable devices really helped me give meaningful conversation topics and critical thinking responses. I'd advise anyone trying to get into any startup company to get your hands dirty before hand to get an authentic exposure to the problem space of their products.
