Very positive onsite interview experience. The interviews are well tailored and they are great hands-on practice. Before the onsites, had 2 60min online HackerRank coding challenges (2nd needed as the 1st interviewer was not convinced of my CompSci fundamentals). After those, got invited to a first onsite consisting of 3 interviews. First was Front-end coding - code an app inside a jsfiddle given a data endpoint. 2nd was Debugging - Given a Java codebase and a user complaint, figure out what the issue is and fix it - nothing too complicated. 3rd was Decomposition - given a dataset related to a problem, figure out a system that uses that data to solve the problem. The interviewers are interested in your way of tackling and splitting up a larger problem into manageable deliverables that work. Got positive feedback after the on-site, and they called me again for a fit/modivation. This last one was a bit unsettling and rushed. The interviewer was typing everything on their laptop and it was more of an interrogation rather than a conversation.

Phone chat with recruiter, followed by technical phone interview in ~2 weeks. The technical interview involved discussing prior/current projects, and a coding question in the Hackerrank environment. Interviewers/recruiters answered all my questions and were always quick to respond.
