Fidelity Technical Interview: Coding, SQL & Projects
The Fidelity technical interview for tech roles in the 2027 intake is a deep dive into your engineering ability: live coding, SQL problems, CS fundamentals, and a forensic walkthrough of your own projects. It usually follows the online coding test. The test filtered for minimum competence; the interview checks whether your skills — and your CV — survive close inspection.
Coding and SQL in the Fidelity Technical Interview
Expect one or two live coding problems at medium difficulty: data structures, algorithms, string or array manipulation, sometimes a practical task like transforming data. You will think out loud while you code — the interviewer is evaluating your problem-solving process, not just the final answer. SQL comes up often: joins, aggregations, window functions, query optimisation. Write clean code, handle edge cases, and talk through your trade-offs instead of coding in silence.
The Project Deep Dive
This is where padded CVs die. "Tell me about your project" turns into architecture questions, design decisions, what broke and how you fixed it, and why you chose one approach over another. Interviewers keep digging until they find the boundary of what you actually understand. If you listed a technology you barely touched, this is the moment it gets exposed. Know every project on your CV at a level where you can defend each decision.
How to Prepare for the Fidelity Technical Interview
Practise live coding out loud — narrating your thinking is a separate skill from solving silently. Drill SQL until joins and window functions are automatic. Rebuild your projects mentally: architecture, key decisions, failures, lessons. Prepare honest answers for what you don't know; "I haven't used that, but here's how I'd approach it" beats bluffing every time. Our 2027 Fidelity International Online Assessment Tutorials includes the real coding, SQL, and project questions from Fidelity technical interviews, with model approaches for each.
Bluffing Has a Half-Life of About Ten Minutes
Technical interviewers at Fidelity have one job: find out what you actually know. Exaggerated CV claims survive roughly ten minutes of follow-up questions before collapsing — and a collapsed claim poisons everything else you said. For the 2027 intake, the candidates who get offers are the ones whose real skills match their CVs. Audit your CV honestly, prepare your projects properly, and walk in with nothing to hide.
