Online test, then 2 hour phone screen. I'm told some candidates are asked to complete a take-home quiz. Online test: quite interesting and difficult, it asks a few simple coding questions (in this code sample, what is the value of x?) in many different languages. Then it asks a few situational questions (if you need to scale this web-server, what would you do?). Strongly biased towards generalists / full-stack web engineers who know a lot of languages (then again, those engineers seem to be in the most demand), and probably more passable if you read HN / know a lot about backend web engineering. Phone screen: some short answer / situational questions, build several projects in a language of your choice (such as a game), debugging a project they send you, and a few others (all described in other glassdoor reviews). Moderate difficulty, no bad questions here - almost everything was relevant to my job. The interview process is open to all types of software engineers, but I doubt an embedded system engineer could pass it - it's heavily weighted towards web engineers. Getting to skip phone screens for these companies is awesome, and it means they are usually pitching you rather than the other way around.
