Hire NestJS Developers
who actually ship Nest apps the team can actually own

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.

A great NestJS developer treats DI as a design tool, not a magic ceremony. The good ones organise modules by domain, write interceptors that earn their keep, and never wire a database client by hand when a provider will do. EasyEnv hands the candidate a real Nest app with a circular dependency and a guard that runs everywhere.

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 NestJS Developer is hard.

Nest fluency hides under "I know Node". DI taste is the senior signal.

Module boundaries are easy to muddle. The interview has to surface clarity.

Interceptors, guards, pipes get over-used. Restraint signals depth.

Prisma versus TypeORM versus raw is a real architectural call.

The fit test

What we measure for a NestJS Developer.

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

Module boundaries

A circular dependency between two modules. They split or invert.

DI taste

A provider used everywhere as a god service. They split by responsibility.

Guards and interceptors

A guard applied globally. They scope to the route.

Persistence

A Prisma query missing transaction boundaries. They wire interactiveTransaction correctly.

Testing

A controller test using the real database. They mock at the right layer.

AI collaboration

Allow AI for refactors and grade whether they ran the e2e suite after.

The stack we put in front of them.

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

Sample challenges

What a NestJS 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 forwardRef tower

Scenario

A Nest app with two modules importing each other via forwardRef. The graph is open.

What you learn

Whether they invert dependency or extract a shared kernel.

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 Nest code that papers over circular deps with forwardRef. EasyEnv records prompts so you see whether the candidate ran the e2e suite after the LLM-suggested change.

Allow or block AI per question, not per interview

Full prompt and response history replayed in the review

Role FAQ

Hiring a NestJS Developer, answered.

Yes. gRPC, Kafka and Redis transports can all be pre-wired with a sandbox broker.

Yes. Apollo and Mercurius can be set up in the workspace.

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.
