A few years ago, a technical interview mostly tested one thing: can you write correct code, from memory, under pressure. That bar has quietly shifted — and a lot of developers preparing for interviews right now haven't fully clocked it.
AI coding assistants are part of daily work at most companies now, from big IT services firms to small product teams. Interview panels have adjusted to that reality faster than most prep guides have.
What's actually different now
Interviewers care less about whether you can produce a function from scratch, and more about whether you understand what code is doing and why. It's increasingly common to be handed a piece of AI-generated code and asked to find the bug, justify a design decision, or optimize it — instead of writing something from zero on a whiteboard.
Some companies go further and let you use AI tools during the technical round, then evaluate how well you direct the tool, verify its output, and catch its mistakes. The skill being tested has moved from "can you write code" to "can you reason clearly with code as your material."
Three things I keep seeing candidates get wrong
Treating a finished course or degree as the finish line.
Completing a syllabus tells an employer you were exposed to concepts. It doesn't tell them you can apply those concepts to a messy, real-world problem — which is exactly what open-ended interview scenarios are designed to expose.Leaning on AI tools without understanding the output.
Using an AI assistant while practicing at home is fine. The problem shows up when that habit surfaces in a live interview as an inability to explain your own solution. If you can't walk through why a piece of code works, a couple of follow-up questions will make that obvious fast.Underrating communication and debugging skills.
As AI tools take on more initial code-writing, the human value shifts toward reviewing, debugging, and explaining decisions to teammates. Candidates who only practiced writing code — and never practiced talking through their reasoning out loud — often struggle here, even with solid technical knowledge.
What's actually worth practicing
If you're prepping for interviews right now, a few adjustments make a real difference:
- Practice reading and debugging other people's code, not just writing your own — it mirrors what the job looks like today
- Get comfortable explaining your reasoning out loud — more interviews are structured as conversations, not silent coding tests
- Spend time on the"why" behind core concepts — data structures, system design basics, how a query actually behaves — since that's the judgment an AI tool can't substitute for you
Fundamentals still matter — arguably more than before, because they're what separates someone who can direct and verify an AI tool from someone who's just along for the ride.
