Hire Svelte Developers
who actually ship Svelte that stays small and fast

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 Svelte developer leans into the runtime instead of bringing React habits. The good ones reach for runes with intent, design load functions that stream, and ship pages that hydrate without bloat. EasyEnv hands the candidate a real SvelteKit app with a load function that blocks navigation.

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 Svelte Developer is hard.

Svelte 4 versus 5 fluency is uneven. Runes are new and not yet muscle memory.

SvelteKit load functions confuse newcomers.

Stores versus runes versus state is a real choice.

SSR and hydration pitfalls are silent until the lighthouse fails.

The fit test

What we measure for a Svelte Developer.

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

Reactivity (runes)

A piece of state that should be $state and is not. They migrate cleanly.

SvelteKit load

A load function blocking navigation. They stream with await blocks.

Stores hygiene

A writable used as a god store. They split by feature.

SSR and hydration

A component that diverges between server and client. They find the timing.

Forms

A form action that lacks progressive enhancement. They use use:enhance properly.

AI collaboration

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

The stack we put in front of them.

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

Sample challenges

What a Svelte 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 page that waits on everything

Scenario

A load function that awaits four data calls before render. The waterfall is visible.

What you learn

Whether they stream with await blocks and parallelise.

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 SvelteKit load functions that await everything in serial. EasyEnv records prompts so you see whether the candidate ran the perf spec 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 Svelte Developer, answered.

Yes. The workspace can be pinned to Svelte 4 with a migration target to 5.

Yes. SvelteKit adapters for Vercel and Cloudflare are 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.
