Applied in December for 2019 Summer internship, got the coding challenge mid-January, followed by 3 interviews within a week apart. Rejection almost two weeks later after radio silence. Interviews weren't very hard, most difficult was probably language trivia. Algorithm questions were rather simple and I only had to provide an outline of how the problem should be tackled; no whiteboard coding. Interviewers were all very friendly. Recruiters weren't very helpful, didn't do much other than arrange interviewers, and wouldn't respond to questions.

Did a Hackerrank, quick phone call with HR, then three video calls with people on the team - two engineers and the manager. The video Interviews did not have coding questions, mostly talked about myself and past experiences.

Started with 2 different Hackerrank challenges in ~September/October, then received notice to interview in mid-December and late January. Interviews with the first team were over Skype, both relatively easy (just normal stuff about Javascript and misc. web technologies). Both interviewers were great -- from what I recall, my last interviewer was the one who was actually hiring for the team. The time from interview to offer was about 1-2 weeks. Other interview wasn't so great -- technical issues came up (no Skype), and interviewer looked very uninterested in the call, since it wasn't his team being hired for. Questions about machine learning were dull, and overally not a pleasant experience. I eventually asked my recruiter to not schedule subsequent interviews for this team. My recruiter was a dream to work with, was open to answering a lot of my questions and even gave me time to wait for other offers before finally accepting this one.
