Key Takeaways
- "Vibe coding" refers to intuitive, AI-assisted development where engineers guide AI rather than typing every line
- Vibe coding interviews assess real-world engineering effectiveness, not memorized algorithms
- Companies using vibe coding interviews report 52% better prediction of on-the-job performance
- The approach favors candidates who can orchestrate AI tools, verify outputs, and make good architectural decisions
- Traditional LeetCode skills have near-zero correlation with vibe coding effectiveness
"Vibe coding" started as a joke among developers - the idea of describing what you want and letting AI figure out the details. But like many jokes, it captured something real. Vibe coding has become a legitimate engineering discipline, and vibe coding interviews are emerging as the gold standard for assessing modern engineering talent.
What Is Vibe Coding?
Vibe coding is a development approach where engineers work collaboratively with AI assistants to build software. Instead of typing every character, vibe coders:
- Describe intent: Explain what they want to achieve in natural language
- Guide iteration: Refine AI output through feedback and direction
- Verify and integrate: Ensure AI-generated code is correct, secure, and fits the larger system
- Make architectural decisions: Handle the high-level choices AI can't make
It's called "vibe" coding because the human contribution is often more about direction and judgment than keystroke-by-keystroke implementation. The engineer provides the vibe - the intent, the standards, the architectural vision - while AI handles much of the mechanical implementation.
Origin of the Term
The term "vibe coding" gained prominence in late 2024 when developers started using it (sometimes ironically, sometimes seriously) to describe their AI-assisted workflows. It captured a real shift: the best engineers weren't necessarily the fastest typists or the ones with the most algorithms memorized. They were the ones who could effectively collaborate with AI.
What started as developer slang became an industry term. By early 2025, "vibe coding skills" appeared in job descriptions, and "vibe coding interviews" emerged as a distinct assessment category.
Vibe Coding Interviews vs Traditional Interviews
The differences are fundamental:
Traditional Interview
- Focus: Can you implement algorithms from memory?
- Tools: Whiteboard or basic code editor, no AI
- Problems: Abstract puzzles with known optimal solutions
- Evaluation: Correctness of final solution, Big-O analysis
- Preparation: Memorize 150+ LeetCode patterns
Vibe Coding Interview
- Focus: Can you build working software with modern tools?
- Tools: Full IDE, AI assistants, documentation, internet access
- Problems: Realistic, ambiguous, resembling actual work
- Evaluation: Process, judgment, output quality, communication
- Preparation: Practice building things with AI, develop verification skills
Why the Shift Matters
Traditional interviews test a narrow skill set that has decreasing relevance. When AI can solve most algorithmic puzzles instantly, testing whether humans can solve them without AI tells us little about job performance.
Vibe coding interviews test what actually matters: Can this person effectively build software in a modern environment? Can they leverage the tools available to produce quality work?
What Vibe Coding Reveals About Candidates
Problem Understanding
Before prompting AI, effective vibe coders ensure they understand the problem. They ask clarifying questions, identify edge cases, and think about architecture. Weak candidates jump to AI prompts before understanding what they're building.
AI Collaboration Skill
How candidates interact with AI reveals a lot:
- Do they write clear, specific prompts?
- Do they break complex problems into manageable pieces?
- Do they iterate effectively based on AI output?
- Do they know when to use AI vs. when to code manually?
Critical Evaluation
AI-generated code isn't always correct. Strong candidates:
- Read and understand AI output before accepting it
- Identify bugs, security issues, and edge cases
- Test AI-generated code appropriately
- Know common AI failure patterns
Architectural Judgment
AI can generate code but struggles with system design. Vibe coding interviews reveal whether candidates can:
- Make appropriate technology choices
- Design for maintainability and scale
- Balance competing concerns (speed, quality, simplicity)
- Think beyond the immediate task
Communication
In vibe coding interviews, candidates verbalize their thinking. This reveals:
- Technical communication skills
- Reasoning process and problem-solving approach
- Ability to explain decisions clearly
- How they'd collaborate with teammates
Implementing Vibe Coding Interviews
Design Realistic Problems
Effective vibe coding problems are:
- Ambiguous: Require clarification and judgment, not just execution
- Realistic: Resemble actual work (building features, fixing bugs, improving systems)
- Appropriately scoped: Achievable in 60-90 minutes with AI assistance
- Open-ended: Allow multiple valid approaches
Example Problems
Problem: Feature Development
"Build a user notification preferences page for our React app.
Users should be able to configure which notification types
they want to receive and through which channels (email, SMS, push).
Use the existing API patterns in the codebase."
Problem: Bug Investigation
"Users are reporting that search results sometimes include
duplicates. Investigate the issue, identify the root cause,
and implement a fix. The relevant code is in /src/search."
Problem: System Improvement
"Our image upload endpoint is slow for large files.
Profile the current implementation, identify bottlenecks,
and improve performance. Document your changes."Provide Full Context
Unlike traditional interviews, vibe coding interviews give candidates:
- Access to a realistic codebase
- Full AI tool access (Claude, Copilot, ChatGPT, etc.)
- Documentation and internet access
- The same environment they'd use on the job
Observe the Process
The outcome matters, but the process matters more. Observe:
- How candidates approach the problem initially
- Their AI prompting strategies
- How they evaluate and test AI output
- Recovery from mistakes and dead ends
- Time management and prioritization

Common Objections Addressed
"This doesn't test real programming skills"
It tests the programming skills that matter for the job. If engineers use AI daily at work (and they do), why test them without it? We don't test drivers without cars or writers without keyboards.
"Candidates might cheat with AI"
The whole point is that AI assistance is allowed and expected. There's nothing to "cheat" with. What matters is how effectively candidates use the tools available - exactly like on the job.
"AI will do all the work"
Try giving AI a complex, ambiguous problem and see what happens. AI can generate code, but it can't understand requirements, make architectural decisions, verify correctness, or debug complex systems. These human skills are exactly what vibe coding interviews assess.
"Traditional skills still matter"
Absolutely. Strong fundamentals help you use AI more effectively, evaluate its output better, and know when something is wrong. Vibe coding interviews still assess these skills - they just do it in a realistic context.
