Hire .NET Developers Who Know Modern C#
Modern .NET is fast, cross-platform, and open source. Assess candidates on C# language features, ASP.NET Core, and EF Core with a real runtime.
Modern runtime
Framework-specific questions
Integrity detection
Faster time to offer
Everything you need to hire .net engineers
Real .NET 8 runtime, C#-specific questions, and integrity detection built for .NET hiring.
.NET 8 LTS runtime
Full CoreCLR with C# 12, records, primary constructors, and minimal APIs — modern .NET only.
.NET MCQ library
Curated questions on async/await, LINQ, records, DI, middleware pipeline, and EF Core.
Live ASP.NET execution
Candidates start a minimal API or MVC app inside the assessment and hit endpoints — no Visual Studio.
AI code review
Claude-powered analysis of idiomatic C#, async correctness, and DI/architecture choices.
Pair-programming interviews
LiveKit video + collaborative C# editor for live .NET sessions.
AI-proof integrity
Code coherence AI flags ChatGPT-generated C#; keystroke biometrics catch takeovers.
.NET templates
Backend ASP.NET Core, library, and console .NET templates calibrated by seniority.
Time analytics
Measure time-per-task to calibrate difficulty.
Built-in pipeline
Job posts, kanban pipelines, structured feedback, PDF reports.
Built for .NET hiring, end to end
Skill signal, integrity, and pipeline — all in one platform.
Test modern C# + ASP.NET Core
Modern .NET looks nothing like .NET Framework. Records, minimal APIs, source generators — great .NET hires use them fluently. ClarityHire runs .NET 8 LTS so you test current skill.
- .NET 8 LTS runtime with C# 12
- Minimal API + MVC execution
- EF Core + LINQ against seeded DBs
Catch ChatGPT-generated code before you hire
LLM-generated code arrives as large clean pastes with no iterative debugging. Authentic coding shows typing rhythm, edits, and refactors. Code coherence AI plus keystroke biometrics score the session, not just the output.
- Edit pattern analysis (type → test → refactor)
- Keystroke biometrics detect takeovers mid-session
- Per-signal authenticity score on every submission
From application to offer in one platform
Post the role, invite candidates, run assessments, schedule live interviews, collect structured feedback, and export a PDF report — all without leaving ClarityHire. No stitched-together ATS, video tool, and assessment platform.
- Job boards with branded careers page
- Kanban pipelines with stage automations
- PDF hiring reports for stakeholders
From posting to offer in four steps
Post the role
Use a ready-made template or build from scratch. Embed the posting on your branded careers page in minutes.
Invite candidates
Send assessments by email or CSV bulk import. Each candidate gets a unique, revocable token-protected link.
They build, you watch
Candidates code in a real Monaco editor with integrated execution. Integrity signals run silently in the background.
Interview + offer
Top candidates advance to a collaborative video interview. Structured feedback, PDF report, offer letter.
Frequently asked questions
What .NET topics can I assess?+
Modern C# (records, pattern matching, primary constructors, async), LINQ, nullable reference types, ASP.NET Core (DI, middleware, filters), EF Core (change tracking, query translation), testing (xUnit, NSubstitute), and performance patterns.
Do candidates need Visual Studio?+
No. The .NET SDK runs inside the sandbox. Candidates use the Monaco editor with OmniSharp-style completions, compile with dotnet, and test inline.
How do you detect if a candidate used ChatGPT or Copilot?+
Code coherence AI analyzes the edit pattern of every session. LLM-generated code typically arrives as large clean pastes with no iterative debugging — those patterns get flagged with evidence. Keystroke biometrics catch takeovers mid-session, and paste events are logged with code-size correlation.
Can I run live pair-programming interviews?+
Yes. LiveKit-powered video plus a collaborative Monaco editor (Yjs CRDT) lets you and the candidate co-edit in real time. Recording, transcription, and structured scorecards are built in.
Do I still need a separate ATS?+
No. ClarityHire includes job boards, candidate pipelines, stage automations, bulk CSV import, and PDF reports. Most teams replace their ATS + assessment tool + interview platform with a single ClarityHire subscription.
