Round 1: 30 minute hiring manager phone call with questions like "What is a product manager" and questions about your experiences and resume.
Round 2: onsite interview

I applied in-person. The process took 1 day. I interviewed at Seek Thermal (Goleta, CA) in Dec 2014
Interview
Went for a 1:1, submitted resume, showed around and introduced to staff and then asked questions. Lengthy podium lecture from Scott on purpose and job culture. Offer made and approved, started work the next week.
