HKEX Coding Test: What to Expect & How to Prepare
The HKEX coding test is a timed online programming assessment for technology roles in the 2027 intake. Expect algorithmic problem-solving questions — data structures, string and array manipulation, and basic complexity reasoning — delivered on a platform like HackerRank or Codility. If you cannot write working code under pressure, you fail. It is a hard gate with no charm offensive to save you.
What the HKEX Coding Test Is
The HKEX coding test screens technology-track applicants before any interview. You receive a link with a set deadline, usually 60-90 minutes, and solve 2-4 coding problems in a language of your choice (Python, Java, and C++ are typically supported). Problems range from straightforward implementations to medium-difficulty algorithm questions. Partial credit exists for passing test cases, so even incomplete solutions earn points.
What the HKEX Coding Test Assesses
It assesses whether you can actually code, not whether you can talk about coding. The test measures algorithmic thinking, edge-case handling, and code correctness under time pressure. HKEX technology teams build and maintain market infrastructure — they need engineers who produce working code, not whiteboard theorists. Recruiters look at test scores as a hard filter; below the cutoff, nothing else on your CV matters.
How to Prepare for the HKEX Coding Test
Grind timed problems, not tutorials. Focus on arrays, hash maps, strings, basic graph traversal, and sorting — these cover the bulk of screening-level questions. Practice writing code that compiles on the first try, because debugging eats your clock. Do full mock sessions: timer on, no notes, target passing all hidden test cases. Drill the habit of checking edge cases (empty input, single element, duplicates) before submitting.

Code It or Lose It
The FOMO here is brutal and honest: the coding test is a hard threshold. You cannot network your way past it, and a great CV will not compensate for a blank editor. Every week you delay practice, other candidates are solving one more problem set. For the 2027 intake tech roles, assume the bar is set by candidates who grind daily. Start now — the test does not care about your excuses.
FAQ
Which programming languages can I use in the HKEX coding test? Typically Python, Java, and C++ are supported, but confirm the allowed languages in your 2027 intake invitation.
How many questions are in the HKEX coding test? Usually 2-4 problems in a 60-90 minute window. Check your invitation and the official HKEX careers page for current details.
Do I need to pass all test cases in the HKEX coding test? Not necessarily — partial credit is common. But more passing test cases means a higher score and a better shot at the next stage.
Is the HKEX coding test proctored? Many online coding platforms include webcam or plagiarism monitoring. Treat it as a closed-book exam and follow the rules in your invitation.
