ENGINEERING HIRING, GROUNDED IN REAL WORKUNDERSTAND. SOLVE. BUILD.

Real repos.
Real problems.
Real engineering.

See how candidates navigate a codebase, diagnose a problem, and build a solution.

AxLark turns practical engineering work into evidence your team can review.

Illustrative bug-fix task: fix a failing checkout in an existing commerce repository.
Built around the work engineers actually do.READ THE CODE. FIND THE PROBLEM. MAKE IT BETTER.
THE STARTING POINT CHANGES THE SIGNAL01 / THE WORK

Engineering starts
with context.

A real codebase has a history.
A problem has constraints.
A good solution has trade-offs.

That’s the work AxLark puts at the centre of hiring. Give candidates a repository and a meaningful problem. See how they understand what’s there, decide what matters, and make a change that works.

01

Existing code

Read the structure.
Understand the relationships.

02

A meaningful problem

Diagnose a bug, add a capability,
or improve an existing design.

03

A working solution

Implement, test and submit
a change you can inspect.

ONE CONNECTED WORKFLOW02 / HOW IT WORKS

From a real problem
to a clearer decision.

Keep the task, the candidate’s work and the review connected.

01

Set the scene.

Build the exercise around a repository and a practical task. Set expectations, timing and review requirements.

Let them work.

Invite candidates into a focused coding environment. They explore the code, implement their approach, run tests and submit.

See the thinking
in the work.

Inspect the submitted changes, recorded checks and activity. Bring engineering judgment into the review.

THE REVIEW
✓ Submitted solution
✓ Recorded checks
✓ Reviewer rationale
EVIDENCE YOU CAN ACTUALLY REVIEW03 / THE SIGNAL

A score is a result.
The work tells you more.

Look at what changed, how it was tested and how the solution developed. Then record the human judgment behind the decision.

HUMAN JUDGMENT, WITH CONTEXT

What does this
change tell us?

THE APPROACH

Inspect how the candidate navigated the problem.

THE VALIDATION

Review recorded test results alongside the code.

THE DECISION

Capture a rating and an evidence-backed rationale.

HIRING TEAMS

Hire with a clearer view.

Recruiters coordinate the process. Engineering reviewers inspect the work. Technical feedback and review completion stay connected to the evidence.

CANDIDATES

Show how you solve.

Understand the task, get into the code, validate your approach and deliver a solution. A chance to demonstrate engineering in context.

YOUR NEXT ENGINEER IS A PROBLEM SOLVER.
