See how engineers think before you interview them

ProdSimulator drops candidates into real production scenarios - incidents, trade-offs, pressure - and shows you how they actually behave.

Checking DB first. Might be index regression.

Hiring engineers is costly

1. CVs lie

Polished stories, buzzwords, zero signal. No CV scoring tells you who's worth interviewing.

2. Screenings are time-consuming

Screening through tens or hundreds of candidates takes weeks. You miss the best ones.

3. Technical interviews are expensive

At the end, only engineers can tell you if a candidate is a good fit. But by then it's too late.

4. AI makes interviewing harder

Candidates can be prepped. Homework tasks get written by AI. The “signal” in traditional interviews keeps dropping. It's much harder to spot what matters most.

Software engineering is not about syntax.
It’s about decisions under pressure.

So we built a way to measure exactly that.

Drop candidate into a real situation

Invite candidates with a simple link. No setup, no coding tasks. They enter a short, realistic scenario that mimics real engineering work.

Let them act under pressure

Candidates respond to real situations - incidents, trade-offs, team messages. No predefined answers. Just decisions.

Observe how they think

We don’t score answers. We evaluate behavior - prioritization, reasoning, risk awareness.

Checked last 15 minutes: 27 duplicate transaction IDs, all from one retry path. Isolating the worker now.

Verifies before acting
Reasoning:
Focused on gathering concrete examples before action.
Balanced urgency with validation.

Jumps to mitigation
Reasoning:
Acted on assumptions without verifying the source of the issue.
Potential risk of masking the root cause.

Strong causal reasoning
Reasoning:
Systematically isolated the failure domain before making changes.
Clear communication with stakeholders.

What this shows you about a candidate

>

What they do first

Do they start with the most important problem, or waste time on the wrong thing?

>

How they solve problems

Do they work through the issue step by step, or make random guesses?

>

How they communicate

Can they explain what is happening clearly to other people?

>

How they make decisions

Do they stay calm and make sensible choices when the answer is not obvious?

This gives you real hiring signal, not polished interview answers.

Built for engineering leaders and recruiters

Engineering leaders

Quickly identify candidates who behave like real production engineers. You can also use it to train your own engineers.

HR & recruiters

Replace CV filtering with real signal before interviews. Proceed only with the best candidates.

How do you spot a good engineer in the AI era?

You can optimize your CV. You can even optimize yourself for interviews.

But you can’t fake engineering when systems get messy.

So I built a way to observe decisions instead of answers.

“The best engineers aren’t the ones who know the most.
They’re the ones who don’t panic when nothing makes sense.”

You don’t need better CV scoring.
You need better signals.
