BNP Paribas HackerRank Test: Questions & How to Prepare
The BNP Paribas HackerRank test is an online coding assessment used for technology, quant, and engineering roles. For the 2027 intake, it typically gives you around 90 minutes to solve several coding problems — often 4–6 questions of escalating difficulty — covering algorithms, data structures, and sometimes SQL or debugging, all scored automatically by the platform.
What Is the HackerRank Test?
HackerRank is a third-party coding platform BNP Paribas uses to screen technical candidates. You code in a browser-based editor with a timer running. Typical structure:
- Easy warm-ups — string manipulation, array operations, basic logic.
- Medium problems — hash maps, two pointers, sorting, basic dynamic programming.
- Hard problems — graph traversal, advanced DP, optimization under constraints.
- Possible extras — SQL queries or "fix the broken code" debugging tasks, depending on role.
Partial credit matters: most problems award points for passing subsets of test cases, so a working-but-imperfect solution still scores. The platform runs hidden test cases — your code is judged on correctness and efficiency, not just on the visible examples.
What BNP Paribas Tests With HackerRank
The assessment targets what the job actually requires:
- Problem decomposition — breaking a hard problem into solvable pieces fast.
- Algorithmic efficiency — O(n) vs O(n²) matters when hidden tests include large inputs.
- Code under pressure — writing clean, compiling code with the clock running.
- Edge cases — empty inputs, duplicates, negative numbers; the hidden tests check these.
For quant and markets tech roles, a near-perfect score is effectively required — the candidate pool is strong and the cutoff reflects it.
How to Prepare for the BNP Paribas HackerRank Test
The method is straightforward but non-negotiable: grind timed coding problems at medium difficulty and above, focusing on arrays, hash maps, strings, and basic DP. Always test edge cases before submitting. Do at least a few full 90-minute mock sessions so the time pressure feels familiar.

90 Minutes, Six Problems, No Second Chance
The BNP Paribas HackerRank test gives quant candidates about 90 minutes for roughly six problems — candidates who haven't drilled timed problems collapse halfway through. The pool is full of practiced coders. If you haven't done the reps, you're donating your application.
FAQ
What programming languages can I use? HackerRank supports most major languages — Python, Java, C++, and others. Use whichever you're fastest in.
How much does efficiency matter? A lot. Hidden test cases include large inputs that time out brute-force solutions.
Do I need to finish all questions? Partial credit helps, but for competitive roles you should aim to complete nearly everything.
Is SQL tested? It can appear for data-oriented roles. Check the invitation details and prepare accordingly.
