Hire ASP.NET Developers
who actually ship ASP.NET that the auditors love

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 ASP.NET developer ships minimal APIs that age well, EF Core code that does not query the world, and auth that the security team trusts. EasyEnv hands the candidate a real ASP.NET service with an auth misconfig and an N+1 to fix.

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 ASP.NET Developer is hard.

ASP.NET runs across decades. Controller vs minimal vs MVC fluency varies.

EF Core is the most common production foot-gun.

Authentication / Authorization layering is its own discipline.

gRPC, SignalR, Blazor are all on the table. Few candidates know all three.

The fit test

What we measure for a ASP.NET Developer.

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

EF Core query design

A minimal API endpoint that fires N+1. They projection-fix without breaking the contract.

AuthN / AuthZ

A policy applied to a controller but missed on a minimal endpoint.

Minimal APIs design

A route group with mixed concerns. They organise with endpoint filters.

Perf and allocation

A hot path allocating per request. They reach for spans and pooled buffers.

Observability

An ASP.NET service with no telemetry. They wire OpenTelemetry.

AI collaboration

Allow AI for refactors and grade whether they ran the integration tests after.

The stack we put in front of them.

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

Sample challenges

What a ASP.NET 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 endpoint without a policy

Scenario

A minimal endpoint that bypasses the [Authorize] policy applied to the MVC controller next to it.

What you learn

Whether they apply RequireAuthorization correctly.

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 minimal APIs that forget RequireAuthorization. EasyEnv records prompts so you see whether the candidate ran the AuthZ tests after the LLM-suggested change.

Allow or block AI per question, not per interview

Role FAQ

Hiring a ASP.NET Developer, answered.

Yes. Blazor Server and WebAssembly can be pre-loaded with a representative app.

Yes. A SignalR hub with sticky connections is available 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.
