Interview process

The interview had two rounds: Round 1 was 45 minutes with an engineer on the team. He opened with a behavioural/CV conversation, then moved unexpectedly into a technical exercise: I was given a fintech/asset-management codebase written by an AI agent and asked to review it live. I wasn’t expecting a technical component, so I had to adjust on the spot. Round 2 was with the hiring manager and had two parts: another code review plus a logic puzzle, alongside a behavioural discussion. The code review was a HackerRank CodePair exercise.

Specific questions asked

I was given a fintech / asset-management scenario — investors putting money into different investments, with their money being allocated across them. The functionality was written by an AI agent — classes and functions (e.g. an allocate function). The task: “Review this code.”

The code-review exercise was a HackerRank CodePair task titled “Code Review: Nightly Hospitality Reporting Rollup.” Review the code as if a colleague had opened a merge request for it. Talk us through what you’d say in the review, and which of your comments would stop it being merged. The tests pass. The scenario: a Python module that rolls up one night’s hotel figures (occupancy, ADR, RevPAR) across a portfolio and writes a CSV — with a 6-rule spec, the module under review, and passing tests.
