Why Most Companies Hire the Wrong Developers and How to Fix It

We have worked with companies as a technical intermediary for developer hiring, sitting between the business and candidates to assess fit, vet skills, and make sure both sides are set up for a productive engagement. The patterns of hiring failure we see are consistent enough that they are worth writing down.

The Brief Is Usually Wrong

Most companies come to us with a job description rather than a problem statement. There is a difference.

A job description says: "We need a senior React developer with 5 years of experience and knowledge of TypeScript, Redux, and GraphQL."

A problem statement says: "We have a legacy frontend that is slowing down the team, a new design system being rolled out, and a backlog of feature work that is blocked on the frontend side. We need someone who can own that and drive it forward."

The second version is what actually helps you find the right person. The first version gets you someone who matches keywords on a CV.

Before we start any search, we push companies to define the actual problem. What does success look like in 90 days? What has gone wrong with previous hires in this role? What does the team dynamic look like? These questions reveal what you actually need.

Technical Interviews Test the Wrong Things

Asking a candidate to reverse a linked list on a whiteboard tells you almost nothing about whether they can build maintainable software in a team context. Yet most technical interview processes are built around exactly this kind of decontextualised puzzle.

The interviews that surface useful signal look different. They involve real code, either a take-home task based on a realistic problem or a paired session working through something that resembles what the role actually involves. They ask candidates to talk through decisions they have made, trade-offs they have navigated, and things that went wrong.

A candidate who can articulate why they made a particular architectural choice and what they would do differently is far more useful than one who can recite algorithm complexity but has never reflected on their own work.

Culture Fit Is Being Used to Mean the Wrong Thing

"Culture fit" is often used as a proxy for comfort, meaning hiring someone who reminds you of people already on the team. This is how engineering teams become homogeneous and brittle.

What you actually want to assess is whether someone can work effectively with your team, communicate clearly, handle disagreement constructively, and grow within your context. That is different from whether they seem like someone you would want to have a beer with.

We push clients to separate "works well with this team" from "is like people already on this team." The former is a legitimate bar. The latter is a bias.

The Probationary Period Is the Most Underused Tool in Hiring

Most companies treat the first three months as a formality. The best-run teams treat it as a structured assessment with clear expectations, regular check-ins, and defined milestones.

A good engineer who joins a team with no clear expectations and no feedback loop will underperform. Not because they are not capable, but because they are operating without direction. The blame then falls on the hire rather than the onboarding process.

Write down what good looks like at 30, 60, and 90 days before the person starts. Share it with them on day one. Review it together at each milestone. This simple discipline reduces early departures and surfaces problems before they become expensive.

The Common Thread

Every hiring failure we have seen comes down to the same root cause: the company did not know precisely what it needed and was not honest with itself about what it was offering. Fix those two things and the rest of the process becomes significantly easier.
