Have you ever hired a developer who seemed perfect on paper, but things didn’t go as planned? You’re not alone.
Many teams notice a gap between resumes and real-world performance. In software, a CV only tells part of the story. The best hires bring skill, good judgment, curiosity, and a team-first attitude.
In this article, we’ll look at the qualities that set great developers apart and share practical tips to help you hire with confidence.
The Value of Hiring the Right Developer
Good developers help to build user experience, drive product velocity, and avoid expensive technical debt. A bad hire will produce slowdowns, bugs, and flat-out frustration for the team.
When hired right, developers protect the roadmap and create time to innovate. When a developer values his or her work in the context of company goals, he or she creates multiplier effects and accelerates outcomes, all the while lifting the team’s morale.

Closing the loop on hiring decisions matters not just for the next sprint, but for the product lifecycle and company culture.
Think about a recent project that slipped its deadline.
Could the outcome have been different with a developer who took ownership and spotted the architectural risk early? Often the answer is yes. Investing time in hiring pays back in fewer fire drills and more predictable releases.
Many firms advise combining short technical assessments with conversational interviews to reveal both skill and temperament. This blended approach reduces surprises after onboarding and improves long-term fit.
Technical Mastery: Beyond Just Coding
Technical skills are the basics. Find developers who write clear code and use version control well. They should be good at debugging, testing, working with APIs, and using cloud services.
A solid API integration capability also signals versatility in connecting systems efficiently.
True mastery isn’t about knowing every tool, but about building reliable solutions and choosing simple answers when possible.
Real project experience and practical problem-solving matter more than memorizing syntax.
Quick checklist to evaluate technical mastery
- Can the candidate explain a system they built in plain language?
- Do they write tests or at least propose a testing strategy?
- Can they reason about performance trade-offs and scaling?
- Do they use source control effectively and write clear commit messages?
Ask candidates to walk through past code samples or a small take-home task. The behavior during explanation matters. Listen for clarity of thought and the ability to point out trade-offs.
Someone who admits to a mistake in a past design and explains how they fixed it often shows deeper understanding than someone who only lists technologies they know.
Example trade-off conversation: ask the candidate to choose between optimizing for latency or for throughput in a given scenario.
A useful answer will state the metrics they care about, describe a testable approach, and explain rollback criteria. This level of practical detail separates theory from production experience.
Analytical and Problem-Solving Skills
Great developers tackle problems like detectives. They break systems into parts, find the root cause, and suggest fixes that address the real issue.
Look for candidates who explain their thinking clearly, can outline a plan, and are willing to adjust as new information comes up.
Strong problem solvers gather data, test their ideas, and consider the long-term effects of their choices.
In the interview, try a short technical task where the candidate solves a simple problem or optimizes a slow SQL query.
Look for how they formulate their hypothesis, what test they run, and how they revise their plan when the hypothesis is not verified. Candidates who rely on a systematic process will produce less cumbersome solutions.
Communication and Collaboration
Software is a team effort. Developers who can explain complex ideas simply, listen to others, and work toward compromise help the team succeed.
Good communication includes not just talking, but also writing clear documentation, making understandable commit messages, and submitting pull requests that are easy to review.

Strong communicators show emotional intelligence, accept feedback, ask questions, and help their teammates.
Interactive prompt for hiring teams
Pretend you are all a team and have to schedule and design the first part of a new feature. What kind of questions would you think of asking this developer to understand how they communicate?
An example of key topics to gather information on would be how they communicate progress, how they contribute and navigate disagreements, and how they can align their technical decisions and the product vision. During interviews, roleplaying would provide evidence on their real-time responses.
Ownership and Accountability
Ownership is about viewing a feature as something more than an item on your checklist. It is caring about the user experience and following through until you have a working result in production.
Candidates who can take ownership of their previous mistakes and learn from them display a level of maturity. Small behaviors, such as updating documentation, writing tests, or proposing follow-up improvements after a release, demonstrate ownership.
During the interview, specifically ask the candidate for examples that showcase that they have acted outside of their job description to rectify a problem or enhance a process.
Practical question to ask candidates
- Tell me about a time a release did not go according to plan. What did you do, and what changes did you make to avoid that situation again?
The answer to the question will help identify if the person is blaming the process or identifying solutions.
Curiosity and Continuous Learning
Technology changes rapidly. Developers who read, explore, and share knowledge will keep their teams relevant.
Curiosity can exhibit itself in side projects, contributions to open source, or involvement with a community of developers.
Curiosity can also present itself in something as simple as a habit of learning new APIs or tools to solve a problem more efficiently.
Hire based on candidates who have demonstrated a pattern of growth versus candidates who depend only on their past contributions.
This mindset helps teams adapt when requirements shift or new platforms emerge.
Ways to spot genuine curiosity
- Ask candidates what they have learned in the last six months.
- Look for examples of experiments or prototypes they built.
- Notice if they can describe trade-offs between new tools and established ones.
Cultural Fit and Team Alignment
Cultural fit does not mean hiring clones. It means finding people who respect your values and enrich the team.
Look for openness, humility, and a willingness to collaborate across disciplines. A developer who values clarity and empathy will help designers, testers, and product managers do their best work.
Think of cultural fit as a two-way street. During the hiring process, present real scenarios from your workplace to see how candidates respond and whether their approach aligns with your team’s norms.
Team exercise idea
Share a recent user complaint and ask the candidate how they would investigate and prioritize fixes. Their answer will reveal empathy for users and how they balance technical debt with user impact.
Red Flags to Watch Out For
There are certain behaviors that suggest future friction.
- Look for overconfidence without evidence of outcomes, bad documentation habits, and resistance to accepting input.
- Learning new tools/procedures often takes some time, and there’s no need to worsen the challenge of learning by resisting new tools or processes.
- Don’t trust candidates who talk only about their individual accomplishments and have no collaborative context built into their stories.
- Sometimes the warning signs are subtle, such as vague answers when prompted about past failures. Ask a probing question and assess how the candidate responded to obstacles they encountered, and what they learned.
Red flag checklist
- Avoids use of collaborator names or can’t explain team outcomes
- Can’t explain trade-offs in past work
- Downplays quality or testing practice
- Responds defensively when asked about their work
Structured interview questions, along with a simple rubric, can help clarify choices.
Consider asking the candidate to explain a recent technical recommendation, ask them to ‘debug’ a short code fragment, and ask them to endorse what they would plan to measure or do to improve a slow application feature.
Based on each proposed answer, or reasons for scoring, you can assign a score based on:
- clarity of response
- technical correctness
- consideration of intended trade-offs
- team or collaboration.
Use a 1 to 5 scale for each dimension and require at least one example of teamwork. Be sure to discuss borderline responses as a panel rather than unilaterally deciding.
This format reduces bias and emphasizes candidates who demonstrate technical skill/consideration with the desired working style.
