For engineering teams

Hire the engineer, not the test-passer.

Assessly scores every candidate twice, the code and the explanation behind it, so the signal you advance on measures understanding, not just output.

The false positive

A green checkmark is not a hire signal.

01

Take-homes get copied.

A passing submission looks the same whether the candidate wrote it, found it, or generated it. The checkmark can't tell you which.

02

Live interviews don't standardize.

Every interviewer runs a slightly different bar, and senior hours are the most expensive way to discover a candidate can't explain their own code.

03

So the signal is incomplete.

A test that only checks output says nothing about whether a candidate can reason about what they built. That is the part you are hiring.

What dual scoring changes

Read the explanation before the onsite.

Every submission comes back with two scores and the candidate's own reasoning attached. Before anyone books a panel, you already know four things.

01The code is correctSandboxed execution against public and hidden tests, in five languages.
02They can explain whyThe explanation is scored for reasoning and trade-offs, in the candidate's words, not the textbook's.
03The work is their ownSandboxed execution, proctoring, paste tracking, and AI-content detection keep the bar honest.
04They're comparableOne standardized rubric across every candidate and every reviewer, no panel-to-panel drift.

The onsite stops being a screen, and goes back to being an interview.
