Can You Debug Code You Didn’t Write? How AI-Assisted Interviews Are Changing Tech Hiring

Technical interviews have traditionally asked candidates to solve programming problems without much outside assistance. The purpose was to evaluate logic, coding ability and knowledge of fundamental concepts. However, this approach is becoming less representative of how software developers work.

Developers increasingly use AI assistants to generate boilerplate code, explain unfamiliar systems, suggest tests and identify possible errors. As these tools become part of everyday development, some employers are reconsidering whether banning them from every interview stage is still the best way to measure ability.

The result is the emergence of AI-assisted coding interviews. Instead of being judged only on how quickly they can write code, candidates may need to demonstrate whether they can inspect, test and improve code produced by an AI system.

What Is an AI-Assisted Coding Interview?

In an AI-assisted interview, the employer permits candidates to use an approved AI tool during part of the assessment. The candidate might receive an existing codebase, an incomplete function or a system containing deliberate defects.

The task is not simply to ask AI for the answer. Candidates must understand the problem, give the tool useful instructions and determine whether its response is reliable.

An interviewer may ask why a particular suggestion was accepted, how the candidate tested it or what risks it introduced. The emphasis moves from producing code alone to exercising judgement throughout the development process.

Code Comprehension Becomes More Important

AI can generate code quickly, but generated code is not automatically correct, secure or appropriate for the system in which it will run. A developer must be able to understand code they did not personally write.

Candidates may be asked to trace how data moves through a function, identify dependencies or explain how a change affects the rest of an application.

They should be comfortable reading unfamiliar naming conventions and locating the sections that require closer inspection. Reading code carefully is becoming as important as writing it.

Debugging AI-Generated Mistakes

AI assistants can produce convincing solutions that contain subtle problems. A response may use an outdated library, overlook an edge case, expose sensitive information or create inefficient database queries.

During an interview, candidates could be evaluated on whether they recognise these weaknesses. A strong candidate will not accept a suggestion merely because it compiles.

Employers may look for a clear debugging process: reproduce the issue, isolate its cause, test assumptions and confirm that the correction has not created another problem. Candidates should explain this reasoning instead of silently replacing code until the program appears to work.

Prompting Is Only One Part of AI Fluency

Giving clear instructions to an AI assistant is useful, but prompt writing alone is not enough. Employers need developers who understand the task before delegating parts of it.

An effective candidate provides relevant context, defines constraints and asks for an output that can be tested. They may divide a large problem into smaller questions rather than requesting a complete application in one instruction.

Most importantly, they remain responsible for the final decision. AI should support technical reasoning, not replace it.

Software Fundamentals Still Matter

AI-assisted interviews do not eliminate the need to understand data structures, algorithms, testing, security and system design. Those foundations allow developers to recognise when an AI-generated answer is inappropriate.

A candidate who understands performance can question an inefficient solution. Someone with security knowledge can identify unsafe input handling. Without those fundamentals, even a confidently presented AI response may be difficult to evaluate.

How Candidates Can Prepare

Practise working with small, unfamiliar codebases rather than generating projects from scratch. Ask an AI assistant to propose a solution, then inspect every assumption it makes.

Create tests for normal behaviour, edge cases and failure conditions. Try to improve the response for readability, performance and security. You should also be able to complete basic debugging tasks without AI in case part of the interview remains tool-free.

Reviewing current software opportunities on Dynamic Brand Gurus can help candidates identify the technologies, responsibilities and problem-solving skills employers repeatedly request. Use those requirements to choose realistic practice exercises.

AI-assisted interviews are not necessarily easier than traditional coding tests. They measure a different form of competence: the ability to combine technical knowledge with intelligent tool use. The strongest candidates will not be those who make AI produce the most code. They will be those who know when its code is wrong.
