Whiteboard interviews ask a candidate to write code on a surface that does not run, from memory, while a stranger watches. Almost none of that matches the job. The job has a terminal, a failing test, documentation, and the freedom to look things up.
If you want to stop using whiteboards but still need a fair, repeatable signal across every candidate, this is the part most "just do real-world tasks" advice skips: what to actually run, and how to keep it consistent. Here is the process we see work.
Decades of hiring research point the same way: the strongest predictor of on-the-job performance is a work sample, a task that looks like the work itself, not an abstract puzzle solved on a board. Schmidt and Hunter's long-running meta-analysis of selection methods put work-sample tests near the top for exactly this reason.
A whiteboard does the opposite. It removes the tools, adds an audience, and rewards candidates who recently drilled the same algorithm. You end up measuring three things you do not care about: short-term recall, comfort performing under a watcher, and luck of the draw on which puzzle came up. We covered how these invisible factors skew results in The Hidden Interview Variables.
Replace the board with a live session inside a real, pre-configured environment. The candidate gets a terminal, a repo, and a task that resembles a Tuesday at your company: fix a failing service, extend an API, debug a broken deploy.
Three rules keep this fair and scalable:
The hidden cost of dropping whiteboards is drift: every interviewer invents their own task and grades on vibes. Fix that with a shared scorecard tied to observable behavior, not gut feel. Score the approach, the debugging path, communication, and the working result on the same rubric for every candidate. Our practical interview scorecard is a starting template you can adapt.

Real-environment sessions cost more interviewer time than an automated puzzle. For the very top of a high-volume funnel, a quick automated screen still earns its place to clear obviously broken submissions. Use the live, no-whiteboard session for the candidates who pass that filter, where a wrong hire is expensive and the deeper signal pays for itself.
Whiteboards test whether someone can perform coding. A real environment tests whether they can do the job. If your goal is the second one, take down the marker.

A live coding interview environment is more than a shared editor on a call. Here is what it actually needs to include, and how the three common setups compare when you look past the demo.

A whiteboard conversation can describe a distributed system. It cannot show you whether a candidate can operate one when a node dies mid-write. Here is how to build a distributed systems assessment around a real cluster, the failure scenarios worth injecting, and a rubric for scoring what happens next.
