You may hire a developer with great technical skills and hands-on experience. But a developer who can do “clean code” is not always an expert problem solver.
In most cases, experienced developers have to take responsibility for existing projects almost immediately after joining. From communicating with team members to fixing someone else’s work, developers need excellent problem-solving skills as well.
This guide walks you through the 10 questions you must ask while hiring developers with experience. Let’s learn why each one matters beyond technical questions.
Almost every experienced developer can showcase attractive projects they have worked on.
But during an interview, what you can’t immediately see is how they handled unexpected bugs, changing client requirements, missed deadlines, security concerns, or collaboration with designers and product managers.
These are the situations that define whether a developer becomes a valuable long-term asset or an expensive mistake.
Even if you know how to hire a developer, it is important to remember that you are not simply buying coding hours. You are investing in someone who will influence your product, user experience, business operations, and future growth.
Asking this question while hiring developers immediately separates experience from theory.
Rather than asking “Have you built an eCommerce website?”, you must ask them to explain an actual project. Pay close attention as they outline the business problem, technical difficulties, decisions they made, and results.
A skilled programmer doesn’t concentrate solely on technologies. Rather, he will talk about user requirements, performance improvement, scalability, and the impact their work had on the client.
The developer who mentions only programming languages without explaining how he implemented them may not possess enough experience for your project.
There are different technical approaches for each project.
An experienced developer would never suggest React, Laravel, Python, Node.js, Flutter, or .NET just because these technologies are popular. Instead, they will tell you what technology is best for you in accordance with your objectives, budget, timeframe, amount of traffic, and further scalability.
Understanding how to evaluate a developer before hiring often helps to find out whether the developer uses business logic while making their recommendations.
Good developers justify trade-offs. But great developers justify non-selection of alternative solutions.
Every software project brings surprises.
APIs change. Clients’ needs change. Integrations with third parties fail. Problems arise after launch.
What makes an ordinary developer an outstanding one is his/her approach to dealing with these situations.
Do not accept “I always find the way out” as an answer to your question. Look for well-structured answers about debugging, documenting, communication, testing, and contingency plans.
Coding is easy.
But making sure that you write maintainable, scalable, and secure code takes effort.
Questions about code review, testing, documentation, version control, coding standards, and deployment. Developers who automatically start talking about Git, automation, code review, and clean architecture tend to be much more valuable than developers whose only concern is coding features.
One of the least asked but one of the most important questions to ask before hiring a developer.
Technical problems do not lead to the failure of many projects. This is due to the lack of communication.
Find out how often you will receive information, which project management systems they use, how they communicate about delays, and how they will handle feedback during development.
Communication minimizes mistakes and promotes better decisions regardless of changing priorities.
Security should not be considered a secondary consideration after deployment.
How do they handle authentication, data security, secure API's, password encryption, input validation, backup, and vulnerability prevention?
Even for your current small-scale business website, lack of security may lead to costly problems in the future.
Professional developers ensure that security is taken into consideration from the outset.
An efficient programmer should be able to talk about caching, database performance, lazy loading, image optimization, API performance, and monitoring performance.
If they start talking about speed right away, then you are talking to a programmer who knows what business impact means.
Release of an application is not the endpoint. It’s only the start of a process that will see constant improvement.
Inquire about support, maintenance, monitoring, patching, and upgrades to your application post-launch. Good developers know that great products keep getting better long after release.
This question always surprises many of the candidates.
Get them to describe APIs, databases, cloud hosting, and backend architecture to someone who doesn’t know any technicality whatsoever.
Great programmers can bring out complexity while not distorting the facts about it.
It could be the most illuminating question of all.
Less-experienced developers promise the world. Experienced people know where the risks lie.
They will say something about time pressure, lack of clarity on what needs to be done, external dependencies, scalability issues, money, or technical limitations before the project is even started.
Ironically, the developers who can see potential problems coming are probably the best bets to hire.
Knowing what to ask is only half the equation. You also need to recognize the warning signs that could turn a seemingly good hire into a costly mistake.
Watch out for these red flags when hiring a developer:
Hiring developers isn’t about discovering someone who knows every programming language. It is about finding someone who understands business goals, communicates clearly, solves problems logically, and builds software that is designed to grow alongside your business.
Why take the burden of both hiring expert developers and managing projects at the same time?
Let us handle your team building so that you can focus more on project delivery. At Web Idea Solution, we ensure we have dedicated, experienced candidates who are ready to collaborate with your team and contribute to faster project delivery.
Get in touch today and let’s discuss your team requirements.
Review their experience in the field, technical abilities, portfolio, mode of communication, development process, availability, costs, and post-launch support services. Ensure that their strategy is appropriate for your project.
First, you must define your requirements, technology, budget, and deadlines. Then choose your developer based on experience, problem-solving, communication skills, previous work, and reliability rather than simply cost.
Inquire about previous projects with similar scope, the technology stack suggested by them, the development process, testing process, security measures, time frame, and post-launch support.
Examine past projects and get them to justify their technical reasoning for their decisions. You could even set them a small coding problem to gauge their ability to solve problems and code.
Don’t be blinded by their number of years in the industry. See to it that they have experience working on projects with comparable complexity and know the ins and outs of development issues.
Yes. Their portfolio will enable you to evaluate the nature of the work done before and how relevant it is. Just ask them to tell you their exact contribution, problems they encountered, technologies used, and outcomes of the project.
Unrealistic promises, very low prices, bad communication skills, no testing process, lack of security awareness, lack of development procedures, rejection of feedback, and inability to describe experience are some common red flags.
It all depends on your requirements. Freelancers will be appropriate for small or temporary jobs, in-house developers will be more appropriate for continuous internal use, and agencies will make a great choice for complicated jobs.
Select a small technical assignment that is related to your project. You should analyze such aspects as code quality, problem-solving ability, attention to detail, documentation, and communication of their ideas.
Ensure that the scope of the project, deliverables, milestones, payment schedule, source code, intellectual property ownership, confidentiality, timeline, support, change requests, and termination of the agreement are all clearly outlined.
