15 Questions to Ask a Software Developer Before Hiring in Windsor

Hiring a software developer, whether a freelancer, a contractor, or your first in-house hire, is a decision that shapes your project for months. Resumes and portfolios only tell part of the story. The right questions reveal how a developer thinks, communicates, and handles the messy reality of a real project. Here are 15 questions Windsor businesses should ask before hiring, and what good answers sound like.

1. Can you walk me through a project similar to mine?

You want specifics, not generalities: what the project did, their role, what was hard, and what they would do differently. Vague answers suggest thin experience. Follow up by asking to see the actual work or talk to the client.

2. How do you approach a project you have never done before?

Every developer faces unfamiliar problems. Good answers describe a process: breaking the problem down, researching options, prototyping the risky parts first. Bad answers are either false confidence (never a problem) or visible panic. You are hiring a problem solver, not a typist.

3. What is your development process from start to finish?

Even a solo developer should have a process: understanding requirements, designing, building in reviewable chunks, testing, deploying. No process means no predictability, and you will feel it in missed deadlines and surprise bugs.

4. How do you keep me updated on progress?

Listen for specifics: weekly demos of working software, a shared task board, written summaries. I will keep you posted is not a communication plan. The developers who communicate well are the ones whose projects succeed.

5. How do you estimate work, and how accurate are your estimates?

Good developers break work into small pieces, estimate each, and track actuals against estimates to improve. Ask what happens when an estimate is wrong; honest developers will tell you estimates are ranges and explain how they handle overruns.

6. How do you handle changes to requirements mid-project?

Requirements change; the question is whether there is a process. Good answers: changes get discussed, estimated, and approved before work starts. Bad answers: sure, no problem (followed by a ballooning timeline) or visible irritation. You want flexibility with discipline.

7. How do you test your work?

You are listening for more than manual clicking: automated tests for critical logic, testing on real devices and browsers, and a habit of fixing bugs before calling something done. A developer who treats testing as someone else's job will ship someone else's problems to you.

8. How do you handle security?

At minimum, expect awareness of the basics: protecting user data, secure authentication, keeping dependencies updated, and never hardcoding secrets. For anything handling customer or financial data, press harder. Security ignorance is a disqualifier, not a teachable gap you want to fund.

9. Who owns the code and intellectual property?

The answer must be you, on final payment, in writing. Also ask where the code lives during the project; you should have access to the repository from day one. A developer who hesitates on ownership is telling you about future problems.

10. What documentation will I receive?

Without documentation, every future change depends on the original developer's memory. Expect at least a system overview, setup instructions, and notes on the trickier parts. Documentation is part of done, not a favour.

11. What happens after launch?

Ask about the bug-fix warranty period (30 to 90 days is typical), ongoing maintenance options, and response times. Also ask what happens if they become unavailable; you need to know your project does not depend on one person's continued existence.

12. What is your availability, and what else are you working on?

A developer juggling five clients cannot give yours real attention. You do not need exclusivity, but you need honesty about capacity and a realistic picture of response times. For in-house hires, this question becomes: why do you want this role?

13. How do you stay current with technology?

Technology moves fast. Good answers mention specific learning habits: side projects, reading, communities, courses. You are not looking for a buzzword list; you are looking for evidence of curiosity and growth.

14. Can you explain a technical decision in plain language?

Ask them to explain a past technical choice as if to a non-technical owner. This is the single most underrated hiring test. Developers who cannot explain their decisions will frustrate you for the entire engagement; those who can will make every decision better.

15. What would make this project fail, and how do we prevent it?

This is the killer question. Experienced developers can name the real risks: unclear requirements, slow feedback, scope creep, a risky integration. Their answer tells you they have lived through failures and learned. A developer who sees no risks has not been paying attention.

Should I hire a freelancer, an agency, or an employee?

Freelancers suit well-defined, shorter projects. Agencies suit larger builds needing multiple skills and continuity. Employees suit ongoing product development. Match the engagement to the duration and breadth of the work, not just the hourly rate.

What is a fair rate for a developer in Windsor?

Freelancers in the region typically charge less than agencies, and both vary widely with experience. Compare total project cost and the assumptions behind it rather than fixating on the hourly number; a faster, more experienced developer at a higher rate often costs less overall.

How do I check a developer's references properly?

Ask references about communication, reliability, and how problems were handled, not just whether the work got done. Ask what surprised them. And ask whether they would hire the developer again; hesitation is data.
