Hiring Software Engineers: AI Assessment Guide
Software engineer is the highest-volume role most Indian staffing agencies fill. The candidates are abundant; the qualified candidates are not. Most CVs look identical at the surface (Java, Spring, AWS, Agile) and the difference between a senior who has shipped revenue features and a senior who has been at the same maintenance job for 6 years is rarely visible without a structured rubric. This guide is the rubric.
Key skills
Must-have
Production code ownership
Has shipped and maintained code in a live production environment with real users — not just bootcamp projects or maintenance tickets.
Primary language depth
3+ years of focused work in one core language (Java, Python, Go, Node, etc.) with evidence of having debugged non-trivial production issues.
Version control fluency
Daily Git usage including branching, rebasing, code review participation. Should be able to explain a git workflow they have used.
API integration experience
Has consumed and/or built REST/GraphQL APIs. Understands authentication, error handling, retries, and rate limiting.
Nice-to-have
Cloud platform experience
AWS/GCP/Azure hands-on (deployment, not just "I have used S3 once") — accelerates ramp on cloud-native teams.
Container familiarity
Docker for local dev, basic Kubernetes — common in modern enterprise teams.
Testing discipline
Writes unit/integration tests as part of normal flow, not an afterthought.
Open-source contributions
Public GitHub activity is one of the strongest signals of self-driven learning and code quality.
Interview questions (8)
Walk me through the most complex bug you have debugged in production. What was the symptom, the root cause, and how you found it?
What to listen for
Specific technical detail (not "the system was slow"). Investigation method (logs, profiling, hypothesis testing). Honest acknowledgment if it took multiple wrong turns.
Tell me about a feature you owned end-to-end — design through deployment. What were the trade-offs?
What to listen for
Real ownership signal. Awareness of trade-offs (performance vs simplicity, build vs buy). Mentions stakeholders, not just code.
How do you decide when to write a test vs ship without one?
What to listen for
Pragmatic answer ("when the code path is critical or the failure cost is high"), not dogmatic ("always test everything"). Real engineers do not test everything.
Describe a time you disagreed with a tech decision your team made. What did you do?
What to listen for
Evidence of disagreeing-and-committing. Not "I quit." Not "they were idiots." Senior engineers escalate, document, and execute.
How do you stay current with new tech in your stack?
What to listen for
Specific sources (this newsletter, that podcast, this Discord). Generic "I read blogs" is a yellow flag.
What is the worst code you have ever shipped to production? Why did you ship it?
What to listen for
Honesty + context. The answer "I have never shipped bad code" is a hard red flag — they have not shipped much.
How do you approach a codebase you have never seen before on day one?
What to listen for
Reading entry points, running it locally, asking specific questions, drawing the dependency graph. Not "I read every file."
What is one piece of feedback you got in the last year that changed how you work?
What to listen for
Specific feedback + specific behavior change. Vague "I learned to communicate better" is a yellow flag.
Evaluation rubric
Score each candidate against these weighted criteria. Total: 100%.
| Criterion | Weight | Signal |
|---|---|---|
| Production ownership depth | 30% | Multi-year ownership of services with real users. Specific anecdotes about production incidents. |
| Technical communication | 25% | Can explain decisions and trade-offs to a non-engineer in two sentences. |
| Code quality habits | 20% | Tests as part of normal flow. Code review participation. Refactoring instincts. |
| Learning velocity | 15% | Specific examples of recently learned tech. Public contributions or learning artifacts. |
| Collaboration | 10% | Disagree-and-commit examples. Mentorship or documentation contributions. |
Red flags
6+ years at one employer with no internal role change — likely missing growth
CV lists 12+ frameworks with no depth signal in any
Cannot describe a single production incident in 5 minutes of probing
Job hops every 8–10 months — likely culture-fit issues
Refuses any take-home or paired coding (some pushback is fine, blanket refusal is not)
