What actually matters in a 2026 technical interview
Coding rounds have changed shape. Here's what's still worth practicing and what's a waste of time.

The format of a technical interview has shifted more in the last few years than in the decade before it. AI coding assistants are now assumed tools, not banned ones, at a growing number of companies — which means the bar has moved from "can you write this loop from memory" to "can you reason about a system, debug something broken, and explain your choices out loud."
What's worth practicing
Whiteboard-style algorithm puzzles still show up, especially at larger companies, so they're not worth ignoring entirely. But the return on practicing system design conversations, debugging exercises against real (if simplified) codebases, and just narrating your thought process out loud has gone up. Interviewers are increasingly grading the reasoning, not just the final answer.
The behavioral round didn't go away
If anything, it matters more now that technical execution is easier to accelerate with tooling. Concrete stories — a specific bug you tracked down, a tradeoff you made under a deadline, a disagreement with a teammate you resolved — carry more weight than generic claims about being "a team player." Prepare three or four of these in enough detail that you could answer three different follow-up questions about each one.
Don't skip the questions you ask back
The questions a candidate asks at the end of a round are still one of the most-remembered parts of an interview loop, and most candidates waste the slot on things they could have found from a company's careers page. A better use of it: ask about something specific to the team you'd join — how they handle on-call, what the last incident postmortem looked like, what they'd change about their current process if they could. It signals you're already thinking like someone on the team.
