Pretty straightforward OA + technical interview where I solved a HackerRank problem. The problem was confusing to understand at first, but that might just be specific to my interview. Definitely a smooth interview, but the questions were unnecessarily complicated.

Asked me to parse an org for the OA.

I was given an employee, their manager, and their employee ID. I had to be able to print the entire org in indent style, showing the manager-to-employee relationship.
