Timed take home assignment (3 hours). Didn't require any significant algo/ds knowledge but the question itself was pretty poorly written.. it used acronyms before actually defining them and the simple example they gave wasn't clear in how it mapped to the actual problem. Also, a large part of the question was just giving basic C# knowledge hints when it would have been a lot more helpful to have had more wording dedicated to clearing up the actual problem itself. Tbh, I didn't do well on it which is also on me, but the hardest part about it was just trying to understand what they were asking for. Hopefully they will improve the instructions or change the problem for other applicants.
