I applied online. The process took 3 weeks. I interviewed at Heartflow (Redwood City, CA)
Interview
I had a initial phone interview with the recruiter followed by a phone technical interview with one of the technical executives and then had an onsite interview with four people. Overall the company looked promising, but for reasons that I couldn't care less, they decided not to move forward with me.
Interview questions [1]
Question 1
First two technical people asked fairly easy questions. The third guy, who seem to be the architect, didn't seem prepared as he didn't really ask any technical questions. The fourth interview was with an executive. He asked very easy technical questions.
