Interviews/Mobile & Games/Unreal Engine Developer

Hire Unreal Engine Developers
who actually ship Unreal games that survive a frame budget

With EasyEnv we build a fit test for the role. Use it to cut the noise at the top of the funnel, or to go deep on the candidates who matter.

You can even evaluate how this person works with AI. So you hire the engineer who can ship, not the one who looks good in a slide.

Plus the full session replay

A great Unreal developer threads C++ and Blueprints with intent. The good ones know when to drop Blueprints into C++, write replication code that does not desync, and treat the frame budget as the boss. EasyEnv hands the candidate a real Unreal project at 30fps and a multiplayer match that has gone strange.

Refactor calculate_total to use Decimal for currency math, and add a test.

How it works

Three steps. Zero infra to maintain.

Pick the fit test

Use a ready-made challenge or ask us to build one for your stack. Live, take-home, or both.

Send one link

The candidate clicks. A full Linux workspace boots in their browser. No installs, no VPN, no zoom-share.

Review at 2x

Replay the session, read the auto-graded checks, and decide. Most reviews take under five minutes.

The problem

Why hiring a Unreal Engine Developer is hard.

Unreal depth ranges from Blueprint hobby to engine modification.

Replication semantics confuse most candidates.

GC and TArray allocation traps are real.

Nanite, Lumen and Niagara are taste calls.

The fit test

What we measure for a Unreal Engine Developer.

Every area runs inside a real production-like workspace. The candidate works in a browser, the session records itself.

Replication design

A property that should replicate and does not. They explain authority.

Profiling

A scene at 30fps. Insights is open.

C++ / Blueprint boundary

A piece of Blueprint that should be in C++. They migrate cleanly.

Engine systems

A subsystem choice (Niagara vs Cascade, Lumen vs baked). They defend.

Build and PCG

A broken PCG graph. They read PCG logs.

AI collaboration

Allow AI for Blueprint scaffolding and grade whether they playtested before merging.

The stack we put in front of them.

Real tools, pre-installed, accessible from the workspace terminal.

Sample challenges

What a Unreal Engine Developer interview looks like.

Pick from our library or ask us to build a challenge for your stack. Each one is a real workspace, not a snippet.

Challenge 01

The health that did not update

Scenario

A health property that does not replicate to clients. The candidate has both sides.

What you learn

Whether they wire DOREPLIFETIME and the right replication condition.

In the workspace

$ ls challenges/

workspace, runbook.md, README.md

candidate has:

· a real Linux box in the browser
· kubectl, docker, terraform, jq, yq
· cluster, repo and cloud creds pre-wired
· auto-checks running in the background

interviewer sees:

· every keystroke + every command
· terminal + screen recording
· auto-graded pass/fail per check

AI in the loop

Score the engineer, and how they work with AI.

AI writes Unreal config that enables every shiny feature. EasyEnv records prompts so you see whether the candidate read Insights after the LLM-suggested change.

Allow or block AI per question, not per interview

Full prompt and response history replayed in the review

Score "verifies AI output" as a separate signal

Role FAQ

Hiring a Unreal Engine Developer, answered.

Yes. A dedicated server build with Online Subsystem can be wired.

Yes. A PCG-driven open scene is pre-loaded.

No. The workspace runs in their browser. Terminal, editor, ports and dashboards are all served from the EasyEnv workspace, so candidate setup is zero.

Each challenge has automated checks (did the service come back, did the test pass, did the right log message appear) plus a recording your team can replay. Most reviews take under five minutes.

Yes. AI access is a per-interview setting. Block it for fundamentals, then allow it later in the loop to assess AI collaboration separately.
