I submitted my resume and was matched with a recruiter. The recruiter had me fill out a questionnaire about the areas I believed I was most skilled in.

After the technical questions, there was a standard LeetCode-style whiteboard problem. It ended up being a medium-level question, but the hardest part by far was the technical questioning.
