Jump Trading Online Assessment
Jump is engineering-heavy and the dominant screen is a Codility coding OA - long, parsing/simulation-heavy C++ (or Python) problems, a few with a trading flavor, plus a couple of bit/greedy insight tasks. Other tracks branch off: a Crypto Quant Trader coding test with a brain-teaser flavor, a Platform-Engineer/SRE shell quiz, and a multi-hour single-dataset data-science task for Quant Dev / QR. The OA is usually followed by a rapid CS-knowledge phone quiz (~20 questions, allow at most 1-2 wrong).
Software Engineer / Core Dev — C++ / Codility coding OA
The main Jump screen: long statements, heavy string/parsing and simulation, plus a couple of bit/greedy insight problems and a few trading-flavored tasks. Originally C++; the recurring problems (auto-graded in Python here) are below.
- Evaluate a Reverse-Polish-Notation Expression Coding · easy
- RPN Stack Machine with DUP / POP and Error Handling Coding · easy
- Total Length of a Union of Intervals Coding · easy
- Interleave the Digits of Two Numbers Coding · easy
- Largest Number by Rearranging Digits Coding · easy
- k-th Permutation of [1..n] (Factorial Number System) Coding · medium
- Largest Subset With Nonzero Bitwise AND Coding · medium
Quant Trader — Crypto Quant Trader OA
A coding test with a brain-teaser flavor (1.5 hours, ~3 problems): a string case-analysis counting task, a 0/1 knapsack, and a turn-game DP. The two cleanly-specified ones are auto-graded below.
- Gifts Knapsack (0/1 Maximize Importance) Coding · medium
- Move-to-Zero Turn Game (Steps 1, 2, or x) Coding · medium
Platform Engineer / SRE — Shell quiz + DP
A 40-minute screen: ~10 single-choice shell questions (Bash/Linux fluency) then one dynamic-programming coding task. The shell section is below as a timed quiz.
Jump Trading OA — FAQ
What is the Jump Trading online assessment?
Jump is engineering-heavy and the dominant screen is a Codility coding OA - long, parsing/simulation-heavy C++ (or Python) problems, a few with a trading flavor, plus a couple of bit/greedy insight tasks. Other tracks branch off: a Crypto Quant Trader coding test with a brain-teaser flavor, a Platform-Engineer/SRE shell quiz, and a multi-hour single-dataset data-science task for Quant Dev / QR. The OA is usually followed by a rapid CS-knowledge phone quiz (~20 questions, allow at most 1-2 wrong).
What is the format of the Jump Trading OA?
It runs as 3 tracks (C++ / Codility coding OA, Crypto Quant Trader OA, Shell quiz + DP). Software Engineer / Core Dev, Quant Trader, Platform Engineer / SRE — each timed, auto-graded where applicable.
How do I practice for the Jump Trading online assessment?
Work the sample questions above (each with a full worked solution), then take the interactive Jump Trading OA practice on QuantVault. For the full interview, see the Jump Trading interview-questions set.
