When you’re on the hunt for a full-stack developer, a resume full of programming languages and frameworks is a good starting point. But what about the person behind those qualifications? You need someone who can build, troubleshoot, and optimize both the front-end and back-end of an application. And, they should be able to do all that while being a great collaborator, too.
So how do you determine who’s for real and who’s just a resume? Here’s what to look for when you’re hiring a full-stack developer.
They Think Like a Problem-Solver
A standout full-stack developer not only knows how to code, they know how to solve problems. When evaluating candidates, ask them about past projects and challenges they’ve faced. You want someone who will explain how they approached a problem, the trade-offs they considered, and how they arrived at a solution.
They Can Move Effortlessly Between Front-End and Back-End
A full-stack developer should be comfortable working with both client-side and server-side technologies. Whether they’re optimizing a database query or fine-tuning a user interface, they should understand the interplay between different parts of an application. Look for candidates who can discuss both UI/UX principles and back-end logic with confidence.
They Have a Strong Foundation in Core Technologies
The best developers have a solid grasp of fundamental technologies, including:
- Front-end: JavaScript, HTML, CSS, React, Angular, or Vue.js
- Back-end: Node.js, Python, Java, Ruby on Rails, or PHP
- Databases: SQL (MySQL, PostgreSQL) and NoSQL (MongoDB, Firebase)
- Version control & deployment: Git, Docker, AWS, or other cloud platforms
Expecting mastery of every framework isn’t realistic, so prioritize candidates with strong core skills and the ability to learn new technologies as needed.
They Write Clean, Scalable Code
Messy, inefficient code can slow down development and create long-term maintenance issues. During technical assessments, note how a candidate structures their code. Is it readable? Modular? Efficient? You can also ask about their approach to testing and debugging because great developers take pride in writing maintainable, bug-resistant code.
They Communicate and Collaborate Well
Soft skills matter just as much as technical skills. The ideal full-stack developer will work well with designers, project managers, and other developers. Look for candidates who can explain technical concepts in simple terms and demonstrate a willingness to take feedback and collaborate.
They Stay Curious and Adaptable
Technology evolves quickly, and the best developers stay ahead of the curve. Ask candidates how they hone their skills: do they contribute to open-source projects? Follow industry blogs? Take online courses? A developer who yearns to learn will be a huge value to your team.
Finding the Right Fit
Tech know-how is critical, but so is adaptability, curiosity, and willingness to be a team player. When you take a look at the big picture, chances are you’ll see the ideal candidate for you.
