The interview process for the HSBC Financial Engineer (Contractor) role consisted of three stages: Online assessment – A written test covering LeetCode-style problems (easy/medium) and Python fundamentals. 1st Technical Interview – Discussion of the role and responsibilities, followed by questions on core Python, basic Pandas operations, common Linux commands, and Git workflows. 2nd Technical Interview – Conducted by two senior managers; focused on pytest and FastAPI experience, in-depth discussion of previous projects, and overall educational background.

There are a lot of basic CS questions in the first round. And some rarely used wired python features are discussed in the second round. The third round is to complete a tiny coding test project.
