It started with filling out a Rembrandt Profile. It asked questions along the lines of "how would your prioritizes these...", "which of these describes you better...", etc. Then I took the online assessment. It had four parts: a 2-minute series of logic questions to test how quickly you can solve logic problems, an untimed series of logic problems, four leetcode questions, and a neat reasoning section in which they described a made up programming language then asked you questions about it. Then I got the invite to the final virtual interview day which consisted of five virtual interviews. The first interview was a company overview + a software demonstration. The second interview was a role-specific overview. The next interview was a 45-minute design question. The next interview was a 45-minute leetcode question. The final interview was an introduction to the hiring manager to ask any lingering questions.
