I applied online, then scheduled a call to talk to an engineer about the company and any questions I had. It was very casual.

Had to take a proctored online exam that was about 4 hours. There were some very threatening terms if you agreed to take it and failed to uphold their terms while you took the exam.

For the online exam, there were 4 sections.

There was an IQ exam that lasts a few minutes and requires you to answer as many as possible.

The math exam wasn't completely math, as there were irrelevant word puzzles (e.g., if an apple is 40 cents, how much is a banana).

There was an exam based around a programming language they use. It went over some of the functionalities before throwing you into a question asking what is the expected output.

There were 4 LeetCode problems you had to code on a default HTML textbox.
