The Five Things We Evaluate That Most Staffing Companies Skip

When a company hires through a staffing agency, here's what they usually get: a resume, a link to a coding test result, and a one-paragraph summary written by a recruiter who spent fifteen minutes on the phone with the candidate.

That's not vetting. That's forwarding.

After placing 200+ engineers with US product teams, we've identified five dimensions that actually predict whether someone will succeed in a remote embedded role. Most staffing companies evaluate one of them (technical skill) and skip the other four.

The resume problem

Resumes tell you what someone has done. They don't tell you how they did it, how they communicated while doing it, or whether they'd do it differently today. A resume that says "Led migration from monolith to microservices" could mean this person architected the whole thing, or it could mean they were one of twelve engineers who worked on tickets while someone else made all the decisions.

Coding tests tell you someone can solve a bounded problem under time pressure. They don't tell you how that person behaves when the problem is ambiguous, the deadline is real, and they need to coordinate with three other people to ship.

Here are the five things we actually measure.

1. Technical depth, not surface knowledge

We don't ask candidates to recite API signatures or solve LeetCode problems. We ask them to explain decisions.

"You used Redux in your last project. Walk me through why you chose it over server state management. What tradeoffs did you accept?" The answer tells us whether this person understands their tools or just uses whatever the tutorial showed.

We also look at how they debug. We present a production-like scenario with incomplete information and watch how they narrow down the problem. Strong engineers ask clarifying questions. Weak engineers start guessing immediately.

Technical depth means understanding why, not just how. An engineer who knows why their architecture works can adapt when requirements change. An engineer who only knows how will rebuild from scratch.

2. Communication clarity

This is the most important dimension for remote work. And it's the one almost every staffing company ignores.

We evaluate communication in three ways. First, a live behavioral interview conducted entirely in English. We're not grading accent or vocabulary. We're listening for structure: can this person explain a complex idea in a way that a non-technical stakeholder would follow?

Second, a written exercise. We ask candidates to write a brief post-mortem for a fictional incident. We evaluate clarity, structure, and whether they naturally distinguish between what happened, why it happened, and what should change.

Third, we watch how they communicate during the technical interview. Do they think out loud? Do they explain their approach before coding? Do they ask questions when something is unclear?

A developer who communicates well saves their team hours every week. A developer who communicates poorly costs hours. This compounds over months.

3. AI tool fluency

This is the dimension that didn't exist two years ago and now matters enormously.

We're not looking for developers who use AI to write all their code. We're looking for developers who use AI tools thoughtfully as part of their workflow. There's a big difference between "I paste everything into ChatGPT" and "I use Copilot for boilerplate, Claude for architecture discussions, and I always review generated code before committing."

An engineer who uses AI tools well ships faster without sacrificing code quality. We evaluate this by asking candidates to describe their current workflow with specific examples. We want to hear about the tools they use, when they use them, and when they deliberately choose not to.

The best answers include a healthy skepticism. "I use Copilot for test scaffolding but never for security-sensitive code" is exactly the kind of judgment we're looking for.

4. Ownership behavior

Ownership is the difference between a developer who completes tasks and a developer who moves projects forward.

We screen for this with scenario questions. "You finish your feature a day early. The next sprint hasn't started. What do you do?" The answer reveals whether someone defaults to waiting for instructions or looks for ways to contribute.

We also ask about past situations where they went beyond their assigned scope. Not heroics. We're looking for patterns like: "I noticed the CI pipeline was slow, so I spent a few hours optimizing it" or "The onboarding docs were outdated, so I updated them after my first week."

Engineers with strong ownership reduce management overhead. They flag risks early. They fix small problems before they become big ones. They treat the product as their responsibility, not just their tickets.

5. Cultural alignment

This is not "culture fit" in the "would I hang out with this person" sense. That framing leads to homogeneous teams and bias.

Cultural alignment means: does this person's working style match what the client team expects? Some teams are highly structured with detailed specs and formal code reviews. Other teams are fast-moving with rough specs and a "ship and iterate" mentality. A great engineer for Team A might be a terrible fit for Team B.

We evaluate this by understanding both sides. We interview the client about their team dynamics, decision-making style, and communication norms. Then we evaluate whether the candidate's natural working style will mesh or clash.

A developer who thrives in structured environments will struggle on a team that changes priorities weekly. A developer who loves autonomy will be frustrated by a team that requires daily check-ins. Neither style is wrong. The match is what matters.

Why all five matter together

Any single dimension can be strong while the others are weak. A brilliant engineer with poor communication will create bottlenecks. A great communicator with shallow technical skills will slow the team down. An engineer who uses AI effectively but lacks ownership will ship fast and break things.

We weight all five roughly equally because they compound. An engineer who scores well across all five dimensions doesn't just complete tasks: they make the entire team better. They write clear PR descriptions that speed up reviews. They flag risks early so the PM can adjust. They use AI tools to handle boilerplate so they can focus on the hard problems.

This is what it means to vet engineers instead of filtering resumes. It takes more time per candidate. That's why we invest the time before you do.
