Prompt engineering did not disappear when models got better, it changed shape. Here is what the skill actually looks like in 2026, why a resume line or a quiz cannot measure it, and the tasks and rubric that do.
CoderPad is a strong, well-built live coding tool for teams with a steady interview pipeline and a recruiting function to run it. A ten-person startup doing its own hiring is a different buyer with different constraints. Here is what changes, and what to check in any CoderPad alternative for startups before you commit.
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.
Almost every Python candidate can write a comprehension and a decorator. Far fewer can say why the worker grew to 6GB overnight. Here are the tasks that separate them, run on a real box with a real process.
A live system design interview lives or dies on structure, not on which question you pick. Here is a minute-by-minute run sheet for keeping it a conversation, plus when a take-home design doc is actually the better call.
Most backend engineers can write SQL and far fewer can work out why a query got slow last Tuesday. Here is how to interview for that, on a real database with real data volume, and what separates the three levels of answer.
When the candidate pairs with an AI instead of with you, the assessment moves from writing code to judging it. Here is what to watch, how to design a task the model cannot finish alone, and what a strong session actually looks like.
Hiring managers are now expected to judge how well candidates work with AI, mostly without having done it themselves on real work. Here is the minimum literacy you need to run that round honestly, and the four questions that expose whether you have it.
The first infrastructure hire is not a scaled-down platform engineer. Here is what the role really is at that stage, why tool-list interviews mislead, and four scenarios that show whether someone can work inside a system nobody documented.
Time to hire is mostly waiting, not interviewing. Here is where the days actually go, which ones you can remove without lowering the bar, and the two changes that cut the most.
Every vendor calls its test a practical developer assessment and none of them define the word. Here is a four-question test you can run on any assessment in five minutes, worked through on a real example, to tell a work sample from a puzzle wearing a nicer outfit.
