Very good. Very casual conversation with the CTO. Not too much extraneous stuff to deal with. Talked a lot about the stack which was fun to learn about. In addition, the location was very good. It had a very nice view.

I applied online. The process took 3 weeks. I interviewed at Starbutter AI (Berkeley, CA) in Jan 2019
Interview
I went through three interviews. The first was behavioral, the second was practical, and the last was behavioral. The behavioral interview was the standard “tell me about yourself” and the technical interview was about something related to what you would actually do in the internship.
