What to Look for When Hiring a Software Engineer or Developer
Learn what to look for when hiring a software engineer, including problem-solving, communication, and key technical skills that matter most.
Within any Software Engineer Recruitment Strategy, hiring a software developer can make or break your roadmap, as a poor hire creates buggy code, slows delivery, and saps team energy what to look for when hiring a software developer goes beyond resumes and job titles to encompass coding skills, system design, problem-solving abilities, testing habits, code maintainability, communication skills, cultural fit, and real-world work samples. This article outlines practical screening steps, interview questions, sample assessments, and onboarding tips to help you confidently identify, hire, and retain a skilled software developer who delivers high-quality work, integrates seamlessly into your team, and drives your projects or business forward with fewer hiring mistakes.
To help with that, Noxx's AI recruiter filters resumes, scores technical tests, and highlights candidates who match your tech stack and team style so you spend less time guessing and more time building.
Summary
Technical ability opens the door, but long-term value comes from product judgment, ownership, and the ability to amplify a team. Eighty-five percent of hiring managers say that soft skills are just as critical as technical skills.
Candidate quality is a significant market issue, with over 70% of hiring managers struggling to find qualified developers, and only 25% of applicants meeting the technical requirements for open roles.
Assessment quality matters more than quantity, as 60% of companies use coding assessments as their primary hiring tool. Therefore, design tests with clear acceptance criteria and limit take-home work to approximately 90 to 120 minutes.
Create scorecards that are compact and role-weighted, starting with 4 to 6 competencies, fixed weights, and anchored scores (for example, 1, 3, 5). Then, conduct a calibration session using around 5 sample interviews to minimize inter-rater variance.
Treat hiring like instrumentation by tracking offer-to-accept conversion, 90-day ramp success, and manager satisfaction at six months, and validate significant assessment changes with at least 20 reviewed candidates before scaling.
Protect candidate experience while preserving rigor, communicate expectations clearly, return rubric-based feedback, and avoid relying on resume screening plus one-hour interviews that fragment predictive signals.

Why is Hiring Great Developers so Challenging?

Hiring top software developers is challenging because supply, speed, and signal all work against you, such as demand outstripping available talent, technology advancing faster than job descriptions, and standard interviews rarely revealing who will actually deliver under pressure. You feel the squeeze whether you run a two-person startup or a 500-person engineering org, because the same mismatches produce missed deadlines, churn, and stalled roadmaps.
Why Is Demand So High and Talent So Scarce?
Employers are competing for the same small pool of experienced engineers, and the math is brutal. According to the U.S. Bureau of Labor Statistics, demand for software developers is projected to grow significantly over the decade. Code.org warns that the U.S. will face a sizable shortage of qualified developers by 2025.
That combination raises salaries, shortens recruiting windows, and forces teams into bidding wars where fit and long-term potential get sacrificed for immediate availability.
How Does the Rapid Pace of Technology Make Hiring Riskier?
Hiring for a single framework or language works when your stack is stable. When introducing new cloud patterns, frontend frameworks, or architectural styles, you need people who can learn quickly and design for change.
In hiring cycles I manage, new engineers typically need three to six months to hit full velocity, so a hire who knows only one toolchain can become a bottleneck rather than a multiplier. That’s why evaluating adaptability and system thinking matters as much as checking off libraries on a resume.
Why is Assessing Technical and Soft Skills So Unreliable?
The failure point is usually the interview format, not the candidate. Whiteboard puzzles reward performance under artificial pressure, take-home projects reward time availability more than engineering judgment, and short behavioral interviews miss collaboration style.
I use timed pair-programming sessions and staged take-homes in recruiting, because long, unpaid projects tend to screen out great but busy candidates, while superficial interviews invite false positives.
How Do Cultural Fit and Diverse Perspectives Conflict During Hiring?
When teams hire for “culture fit,” they often mean “people just like us,” which narrows thinking and increases groupthink. Quiet, highly skilled engineers are frequently misperceived as poor communicators, while more extroverted candidates can sometimes appear to be collaborators.
Good hiring balances psychological safety with challenge; that requires clear, observable measures of collaboration, feedback style, and conflict resolution, not vague gut impressions.
Where Do Speed and Short-Term Pressure Lead Hiring Teams Astray?
What most people overlook is that moving quickly in hiring can amplify late-stage regret. Rushing to fill a sprint gap often prioritizes immediate coding output over problem-solving, ownership, and system design.
I have replaced hires who were technically adequate but unable to communicate tradeoffs, and the cost was often three months of salary plus six months of delayed features and rewrites, because the team lost alignment and momentum.
What Can You Do Differently When Evaluating Candidates Right Now?
Constraint-based opening:
If your process only uses coding tests, then you are blind to collaboration
If you rely only on pair programming, you miss long-form design thinking
Build a layered assessment that combines short code challenges, a take-home design brief capped at reasonable hours, and an asynchronous behavioral case review. That mix reveals technical depth, architectural judgment, and a communication style that avoids forcing candidates into a single artificial format.

What to Look for When Hiring a Software Developer

A truly valuable software developer writes clean, maintainable code and boosts the entire team’s productivity through clear thinking, reliable testing habits, and the ability to translate ambiguous product requirements into pragmatic technical decisions.
You should hire for a cluster of durable signals, such as technical craft, system-level judgment, test-first instincts, and social skills that let engineers shape product outcomes rather than just implement tickets.
Which Technical Skills Separate Solid Contributors from Exceptional Ones?
Look for engineers who can explain trade-offs in time, complexity, and maintainability, providing concrete examples from past systems, pull requests, or incident post-mortems. That indicates they can balance short-term delivery with long-term operability.
Test Automation and Observability, Not Just Passing Unit Tests
Valuable hires design test suites that prevent regressions, reduce flakiness in CI, and include meaningful integration and contract tests. Ask about a time they removed 80 percent of build failures or shortened mean time to detect, not just whether they write tests.
Data Model and Database Fluency
The best backend engineers reason in terms of queries, indexes, and the cost of joins; they can sketch a schema and explain how it will scale under concurrency. That skill reduces late-stage rewrites and performance surprises.
Network and Security Pragmatism
You do not need a full-time network engineer on every team. Still, you do want devs who can implement secure transport, understand latency tradeoffs, and reason about authentication flows when those issues become product blockers.
Language and Tooling Depth Over Language Checklisting
Prioritize individuals who can quickly learn new frameworks and explain why a particular tool was chosen, rather than those who merely list libraries on their resume.
Which Non-Technical Traits Predict Long-Term Impact?
Communication that clarifies tradeoffs. Candidates who can summarize a complex technical choice in two sentences for a PM and five sentences for an engineer will reduce rework and unblock product decisions.
Ownership and product empathy. The engineers who ship impact trace that behavior to owning metrics, customer stories, or a feature from design through deployment and monitoring.
Curiosity that produces evidence. Prefer candidates who publish notes, mentor others, contribute to open-source projects, or run postmortems; these are visible records of continuous learning and teachability.
Adaptability under constraints. High-value hires demonstrate their ability to deliver under reduced resources, shifting priorities, or incomplete specifications, as startups and scaling teams often do not provide perfect requirements.
How Should You Balance Immediate Needs Versus Long-Term Potential?
If you need immediate feature throughput, prioritize engineers with proven shipping records in similar stacks and observable maintainability habits. When building a platform or product, favor systems thinkers who demonstrate a track record of architecting for scale, anticipating failure modes, and coaching peers.
Both paths require measurable signals, such as documented engineering decisions, incident notes, or artifacts of ownership, that you can evaluate during the screening process.
A Practical Screening Checklist That Actually Predicts On-the-Job Performance
Look for artifacts, not phrases: Pull requests with focused commits, readable diffs, and constructive code review threads beat polished résumés.
Test for design-to-deploy competence: Ask for a short take-home that covers design, a test plan, and deployment steps, capped at a few hours so it measures judgment, not free labor.
Verify collaboration history: Evidence of cross-functional work, bug ownership, and mentoring predicts fewer interpersonal breakdowns later.
The Hiring Market Context That Changes How You Should Weigh These Signals
Over 70% of hiring managers report difficulty in finding qualified software developers. That finding, from the State of the Software Engineering Jobs Market report, shows screening must discriminate better than ever because quantity no longer guarantees quality.
Only 25% of applicants meet the technical requirements for open positions. The same 2025 report points out that resumes often inflate capability, so rely on evidence-based evaluation to surface the top quartile rather than trusting background alone.

How to Assess Software Engineer Qualities During the Hiring Process

You should evaluate developers using a repeatable, role-weighted process that combines anchored behavioral interviews, realistic technical tasks, and calibrated team exercises, ensuring that decisions are comparable and defensible. Do not rely on intuition; use clear rubrics, blind scoring where possible, and a short validation loop that ties assessment signals to early on-the-job outcomes.
How Should You Build a Scorecard That Actually Predicts Performance?
Start with a compact scorecard that lists 4 to 6 competencies tied to the role, then assign fixed weights so reviewers know what matters. Use concrete anchors for each score, for example:
1 equals “misses the problem,”
3 equals “solves with coaching,”
5 equals “designs and documents a production-ready fix.”
A rubric works like a referee’s playbook; it keeps different judges calling the same plays. Run a quick calibration session with 5 sample interviews and adjust anchors until inter-rater variance drops to an acceptable level.
What Makes a Technical Assessment Both Fair and Lawfully Defensible?
Design tasks that are short, reproducible, and role-specific, and always include acceptance criteria. Keep take-homes to a maximum expected time, for example, 90 minutes to two hours of focused work, or split longer assignments into two small deliverables so candidates don’t sacrifice evenings.
Make submissions blind for the first pass, and have a separate technical reviewer assess code quality, while a product or PM reviewer scores domain judgment. Because 60 percent of companies use coding assessments as a primary tool in hiring, according to Gloroots Blog, the difference between a practical test and a noisy one is in its design and scoring, not whether you give a test at all.
How Do You Surface Soft Skills Without Letting Bias Win?
Use behavioral questions with strict timeboxed answers and anchored scoring rubrics. Ask every candidate the same three collaboration scenarios, then score their responses against specific examples, not general impressions. Normalize reviewer bias by anonymizing notes before the debrief and forcing each panelist to submit their scores independently before discussion.
Remember that Soft Skills Matter
Eighty-five percent of hiring managers believe that soft skills are just as critical as technical skills when evaluating software engineering candidates, according to Gloroots Blog, so make those behaviors measurable rather than optional.
When Should You Use Live Debugging Versus Take-Home Work?
Use live sessions to observe real-time communication and troubleshooting under pressure, but scope those problems tightly so sessions do not degrade into infinite loops. This pattern appears across interviews and onboarding, where long, context-poor debugging tasks result in wasted time and frustrating feedback.
As the session runs longer, the more context drifts, and suggestions lose focus. If you must run an AI-assisted debugging exercise, provide a clear snapshot of state, test data, and a single failure to fix, then timebox the session to prevent escalation.
How Do You Keep Interviews Defensible and Aligned as You Scale?
Run regular calibration workshops, record exemplar interviews for new interviewers, and require a written decision justification tied to rubric scores before any offer is approved. Audit hires quarterly for a year and correlates initial scores with ramp time and first-quarter impact; if a signal does not correlate, adjust the weight or the question.
Think of this as versioning your hiring process. Keep changelogs for rubrics and guardrails so you can roll back if a change reduces predictive power.
How Should You Measure Whether Your Evaluation System Actually Works?
Track three things:
Offer-to-accept conversion
90-day ramp success
Manager satisfaction at six months
Run small validation pilots whenever you change a primary assessment, aiming for at least 20 reviewed candidates to spot systematic bias or noise. Treat your hiring funnel like instrumentation on a system, not a black box; if scores do not correlate with downstream outcomes, refine the metric, not the person.
How Do You Protect Candidate Experience While Maintaining Rigor?
Communicate expectations clearly, provide reasonable time windows, and return specific feedback using rubric language. Candidates respect transparency and concise feedback more than small perks. A fair process is fast, honest, and predictable, and that preserves your brand while keeping the pipeline healthy.
