These Are the Essential Questions Every Full-Stack Developer Should Ask at a Job Interview

As a seasoned full-stack developer, I‘ve been on both sides of the interview table countless times. One thing I‘ve learned: the interview is a two-way street. It‘s not just a chance for the company to evaluate your technical chops and culture fit, but an opportunity for you to assess if the role and organization align with your goals and values.

Asking thoughtful, probing questions shows you‘re truly interested in the position and thinking critically about what it would be like to work there day in and day out. It‘s a way to glean crucial information you can‘t get from a job posting.

The numbers back this up. A 2019 Glassdoor survey found that 82% of interviewees who asked questions were satisfied with their job, compared to 66% who didn‘t. And according to LinkedIn, on average, candidates ask 2-3 questions in a typical interview. Posing 5+ detailed, role-specific questions can set you apart.

I‘ve compiled the ultimate cheat sheet of questions for full-stack developer interviews, broken down by category. Arm yourself with these to make the most of your next interview and land a fulfilling job you‘ll love. Let‘s dive in!

Questions on Tech Stack & Architecture

As a full-stack developer, you‘ll be working across all layers of the application. It‘s important to understand the specific technologies the company uses on the front-end, back-end, and everything in between. Some key areas to probe into:

What front-end framework(s) do you use and why?

What you‘ll learn: Are they using a modern JavaScript framework like React, Angular, or Vue? A more old-school approach like jQuery? Digging into the rationale behind their front-end choices can reveal a lot about their development philosophy and appetite for innovation.

What it shows them: Frameworks are a hot topic for front-end devs. Asking about it highlights your expertise and shows you care about using the right tool for the job. If you‘re well-versed in their framework of choice, it‘s a chance to showcase that.

What‘s your back-end technology stack?

What you‘ll learn: Is the back-end powered by tried-and-true relational databases like MySQL or PostgreSQL, or are they using more cutting-edge NoSQL solutions like MongoDB or Cassandra? What about the server-side language and framework? NodeJS, Django, Ruby on Rails?

What it shows them: Mastering the full stack means understanding how front-end and back-end technologies interface. Inquiring about the back-end shows you appreciate the big picture and think holistically about application architecture.

How do you handle state management?

What you‘ll learn: For complex applications, state management can make or break the user experience. Are they using a library like Redux or MobX? What about newer approaches like the Context API or GraphQL? Diving into this topic can spark an illuminating discussion.

What it shows them: State management is a common pain point for front-end developers. Broaching the subject proves you understand the challenges and tradeoffs. It‘s a way to flex your architectural acumen.

Questions on Development Processes & Workflow

Technical chops are only part of the equation. To thrive as a full-stack developer, you also need to gel with the team‘s development processes and engineering cadence. A few points to clarify:

What project management methodology do you follow?

What you‘ll learn: Most development shops these days are practicing some flavor of agile, like scrum or kanban. But the devil is in the details. How long are the sprints? What ceremonies do they observe? Who plays what roles? Agile is a broad umbrella, so make sure you understand their specific implementation.

What it shows them: Demonstrating fluency in agile methodologies is a big plus. It shows you know how to function effectively on a development team and collaborate cross-functionally.

What‘s your Git workflow?

What you‘ll learn: Source control is the backbone of any software project. Most teams use some variation of Git Flow, but there‘s wide variation in the wild. Understanding branch management, code review processes, and release cadence is key to hitting the ground running.

What it shows them: This is a chance to highlight your experience with version control best practices. It underscores that you‘re a team player who knows how to collaborate effectively on a shared codebase.

How often do you deploy to production?

What you‘ll learn: Some organizations deploy multiple times a day. Others have a more conservative weekly or monthly cadence. There‘s a growing body of research showing that high-performing IT teams deploy frequently, so this can be a telling metric.

What it shows them: Asking about deployment frequency signals that you understand the importance of getting code into users‘ hands early and often. It shows you‘re thinking about the entire software development lifecycle, not just your small slice.

Questions on Testing & Quality Assurance

Shipping high-quality, bug-free code is the mark of a great full-stack developer. To that end, it‘s important to understand the team‘s approach to testing and quality assurance. Some questions to ask:

What‘s your testing strategy?

What you‘ll learn: Quality teams bake testing into every phase of the development process. Do they practice test-driven development (TDD), where tests are written before the code? Are they doing unit testing, integration testing, end-to-end testing? What tools and frameworks do they use?

What it shows them: Inquiring about testing demonstrates that you appreciate the vital role it plays in the software development lifecycle. It shows you‘re not just a cowboy coder, but someone who understands the importance of building robust, maintainable software.

How do you handle bugs and issues?

What you‘ll learn: Bugs are inevitable. What matters is how they‘re triaged and resolved. Is there a formal bug tracking system? An established process for prioritizing and assigning issues? Clear service-level agreements (SLAs) around response times? These are all important factors.

What it shows them: Asking about bug triage shows that you‘re not afraid to confront the unglamorous aspects of software development. It underscores your commitment to quality and user experience.

Questions on Team Culture & Growth

As a full-stack developer, you‘ll be collaborating closely with other engineers, designers, and stakeholders. Team dynamics and growth opportunities are key to your long-term happiness and success. A few areas to explore:

What‘s the makeup of the development team?

What you‘ll learn: Is it a small, tight-knit team or a larger, more siloed organization? What‘s the ratio of junior to senior developers? Are there separate front-end and back-end teams, or does everyone work across the stack? Knowing the team composition can help you understand your potential role and impact.

What it shows them: Expressing interest in the team makeup demonstrates that you understand software development is a team sport. It shows you‘re thinking about how you can complement and learn from your colleagues.

What opportunities are there for professional development?

What you‘ll learn: The best companies invest in their employees‘ growth. Do they offer formal training and development programs? Tuition reimbursement? Conference travel stipends? Hackathons and other opportunities to experiment with new technologies? Continuous learning is key to staying sharp as a full-stack developer.

What it shows them: Inquiring about growth opportunities shows you‘re committed to your craft and want to keep leveling up your skills. It signals that you‘re looking for a long-term home, not just a stepping stone.

What are your diversity and inclusion initiatives?

What you‘ll learn: Diversity is a hot topic in the tech industry, and for good reason. Research shows that diverse teams perform better and are more innovative. Understanding the company‘s D&I efforts can give you a sense of their values and commitment to building an inclusive culture.

What it shows them: Asking about diversity demonstrates that you appreciate the value of different perspectives and backgrounds. It shows you want to be part of an organization that values equity and inclusion.

Questions to Avoid

While it‘s important to ask questions, there are also some topics that are best avoided in an interview setting. Here are a few examples:

• Don‘t ask about salary and benefits right off the bat. Wait until you have an offer in hand to negotiate compensation.
• Avoid questions that could be easily answered by the company‘s website or a quick Google search. Do your homework ahead of time.
• Steer clear of negative questions about the company‘s competitors or past employees. Keep things positive and forward-looking.
• Don‘t get too personal with questions about the interviewer‘s background or family life. Keep it professional.

The key is to strike a balance between demonstrating your interest and expertise, while staying respectful and on-topic. When in doubt, err on the side of professionalism.

Wrapping Up

There you have it – the essential questions every full-stack developer should ask at a job interview. Remember, this is your chance to peek behind the curtain and ensure the role and company are the right fit for you. Don‘t squander it.

Before your next interview, review this list and jot down the questions that resonate most. Tailor them to the specific role and company, and practice delivering them in a way that feels natural and conversational.
