Hire on process,
not puzzles

VectorBench turns any take-home assignment into a rich source of data that measures real-world process, not just code.

Why VectorBench?

#1

Take-Home, Turbo-Charged

Ship a 2-hour repo challenge that feels like day-one on the job, not homework.

#2

Measure process, not just results

See what tools, prompts, and strategies candidates use to solve your take-home assignment.

#3

LeetCode ≠ Real Work

AI can solve every medium in seconds—why are you still timing bubble sorts?

#4

Minutes-to-Signal

Hiring panel gets green-or-red with a detailed report in minutes—no pair-prog marathon.

THE PROBLEM

LeetCode Tests Trivia—Not Skills

AI solves every algorithm problem in seconds. Hiring teams waste hours on metrics that don't predict performance.

ChatGPT - Two Sum Solution
function twoSum(nums, target) {
const map = new Map();
for (let i = 0; i < nums.length; i++) {
const complement = target - nums[i];
if (map.has(complement)) {
return [map.get(complement), i];
}
map.set(nums[i], i);
}
}
// Time complexity: O(n)
// Space complexity: O(n)
THE SOLUTION

Real Engineering Problems

Candidates debug real code using real tools. Fix tests, not toy problems. Get genuine skill signal fast.

How It Works

Step 1

Select a challenge

Provide your existing take-home assignment, or we'll generate one for you tailored to your stack and role requirements.

Step 2

Candidate fixes bugs & runs tests

Engineers work with their preferred IDE, and setup is as simple as cloning a repository and running a command.

Step 3

10x better data for your hiring pipeline

We'll automaically track and grade the candidate's submission, and provide you with a detailed report.
