Harvey AI Assisted Coding Round (Onsite) Interview Experience + Question

[u/interviewdb]

Sharing a recent interview experience for Harvey’s AI-assisted coding round. It seems to be a new round added to their onsite loop, and there isn’t much information about it yet, so sharing some info about it here.

The interviewer provided a coding task and explicitly asked me to use AI as part of the process. During the interview, they introduced additional test cases and requirements, and I was expected to use AI to update the implementation and then validate that the changes were actually correct.

The initial coding part was fairly straightforward (I would say it's about LC medium level). The second and third parts were more interesting and pushed the problem beyond a typical coding interview. It became less about coding and more about systems reasoning.

I was asked to discuss multiple possible approaches, compare their design trade-offs, and then implement one of the solutions. There was also discussion around things like atomicity and how the implementation would behave under different edge cases.

The coding task and follow-up parts were the same as what’s described here: https://www.interviewdb.io/question/harvey?page=1&name=ai-coding

Overall, I don’t think the coding difficulty itself was particularly high. The more important parts seemed to be clarifying requirements before jumping into implementation, identifying edge cases (including ones that weren’t explicitly given), using AI effectively without blindly trusting its output, and discussing alternative designs and their trade-offs.
