There were one or two phone screens covering basic software engineering skills, but the meat of the process took place in the onsites. These interviews included: - One round of standard engineering interview boilerplate. Covered knowledge of Node and other frameworks, networking, application architecture, etc. Pretty standard stuff, but actually focuses less on "traditional" compsci whiteboarding challenges; ST is a bit ahead of the curve in terms of overcoming the industry's tendency towards 4-year university elitism, and is extremely friendly to bootcamp graduates. - One culture round featuring a panel with members of several teams. This round focused on making sure that a candidate connects well to all members of the org. Relaxed atmosphere, but definitely a little more serious than the average culture segment out there. Come prepared to act like a human being. - One round of discussion about a recently completed project. Be prepared to defend your engineering decisions and take a deep dive into the mechanics of your solution.
