Character.AI Software Engineer interview questions

Recruiter found me on LinkedIn. Had 2 screening conversations, 1 with recruiter, 1 behavioral with manager. Followed up with a React-focused technical screen. Overall interviewer was friendly and question was not difficult, but requires familiarity with some React quirks (ie deep vs shallow copy, callbacks, etc). Focus was more on planning which data structure to be used in advance as functionality builds upon the foundation.
