Real Challenges, Real Skills, Real Confidence
Tired of Tech Tests That Don’t Actually Prove Anything?
Modern coding test platforms are easy targets for AI “co-pilots” and cheat solutions. Hiring managers are left sifting through hundreds of identical code submissions, struggling to differentiate genuine expertise from AI-assisted guesswork.
Why Traditional Platforms Fail
Puzzle-like coding challenges or algorithmic quizzes no longer reflect what real-world engineering requires. Worse, they’re easily gamed by LLMs, shared solutions, or well-rehearsed copy-paste strategies.
That means you risk passing mediocre candidates who can’t handle your production environment—or missing out on gems who don’t shine on toy challenges.
How simstack Changes the Game
simstack is the flight simulator for engineering — a living, production-grade environment where candidates face complex, realistic challenges using their own tools.
You can’t fake real troubleshooting or architectural judgment. There's no single correct “answer key,” so a quick AI prompt won't cut it. Instead, you see each candidate’s actual thought process, communication style, and problem-solving approach under real operational pressure.
The result? A far more accurate signal of who’s genuinely going to thrive on your team—and who isn’t.
Evaluate True Full-Stack Ability
simstack’s environment spans all major engineering disciplines. You can test exactly the areas that matter to your team—and watch how candidates adapt in real time.
Frontend
Assess whether applicants can create responsive UIs under high-demand scenarios. Watch them solve real user-experience constraints and optimize for scale.
Example challenges
- Building offline-ready SPAs
- Handling concurrency in real-time dashboards
- Performance debugging on multi-platform UIs
Backend & DevOps
Go beyond coding tasks: see how they handle microservices, high-traffic events, infra as code, and advanced CI/CD pipelines — or fail to.
Example challenges
- Breaking a monolith into resilient services
- Implementing zero-downtime blue/green deploys
- Real-time observability & incident response
ML & Data
Put data claims to the test with real ingestion pipelines, model deployments, and data scaling. Great for ML-focused roles or data engineering positions.
Example challenges
- Handling streaming data with queue-based systems
- Feature store architectures
- Monitoring live model performance & retraining
Security
Watch how candidates identify and address vulnerabilities in real codebases or infrastructure. Perfect for testing practical security readiness at scale.
Example challenges
- Secrets & credential rotation under time pressure
- Zero-trust network implementations
- Simulated security breaches & incident containment
Custom scenarios
Because simstack is a living environment, we can craft specialized challenges (IoT, HPC, concurrency) that mirror the real “day one” difficulties of your unique stack.
Why simstack for Hiring?
1. Real Production Scenarios
Ditch puzzle-based tests. Challenge your candidates with real outages, concurrency meltdowns, data spikes, security breaches, and more—exactly what they’ll face on the job.
2. Impossible to “Cheat” with AI
Because there’s no single correct answer, AI quick-fixes don’t cut it. You’ll see each applicant’s **true** approach, from initial triage to final deployment.
3. Signal That Actually Matters
Instead of a pass/fail quiz, you get a detailed record of how candidates think, communicate, and collaborate. That’s gold for making informed offers.
4. Scale Your Hiring
Spin up standardized real-world challenges for dozens (or hundreds) of applicants. Focus your time on the top performers whose solutions you really need to see.
How It Works
1. Configure Your Scenarios
Choose from pre-built or custom scenarios matching your stack needs (frontend, infra, data, etc.).
2. Invite Candidates
They’ll tackle each challenge asynchronously, in a real environment, with zero illusions or spoon-fed solutions.
3. Review & Compare
Evaluate all attempts side-by-side with detailed “flight-recorder” style logs of each candidate’s decisions and rationale.
Compare simstack to Other Hiring Solutions
| simstack | LeetCode/Codility | Behavioral Interviews | Take-Home Projects | |
|---|---|---|---|---|
| Challenge Type | Live production-level scenarios | Algorithmic puzzles | Subjective Q&A | Offline & limited scope |
| AI Cheating Risk | Very low (no single “solution”) | High (easy to copy/paste) | High (can rehearse/guess) | Moderate (can still copy patterns) |
| Hiring Confidence | Deep: see real problem-solving | Superficial: algorithmic solutions | Relies on anecdotal evidence | Good, but lacks real-time pressure |
| Scalability | High—automated environment | High but easily gamed | Low: each interview is live | Medium: limited standardization |
