In this post, we’ll share:

  • practical tips to recruit IT candidates
  • web developer interview stages
  • 50+ web developer interview questions

Before you get started, take a moment to confirm that you need to hire a web developer, and not another IT role. Here’s a quick comparison between web developers and related positions.

  • Web designers create the layout and other visual elements of a website. Responsibilities include researching user behavior, creating a website structure, designing wireframes and mockups, and more.
  • Web developers build and maintain websites. Responsibilities include writing and reviewing code, testing web applications, troubleshooting problems, and more.
  • Software developers create software. Responsibilities analyzing user needs, designing each unique piece of a system or application and planning how the work together, building models or diagrams, and more.

Web designers and web developers work closely together, with web developers bringing web designers’ vision to life.

Software developers and web developers both write code, but they create different products.

How to Recruit Web Developers

Before you can start interviewing potential employees, you first need candidates to apply for your web developer role. To attract top IT talent, you need to be realistic about both the job and the job market. These tips will help you hire the ideal web developer for your team.

Be clear and concise in your web developer job description

When putting together the job description, be sure you are communicating your expectations. First of all, what kind of web developer do you need? Generally speaking, web developers can specialize in one of three roles:

  • front-end developers
  • back-end developers
  • full-stack developers

After you determine what kind of web developer you need, then you can elaborate on the other details. What are the minimum qualifications and the “nice to have” qualifications? What are the typical duties and responsibilities?

A strong and accurate job description will attract the right job applicants.

Understand the market and set an appropriate budget

The market for good web developer positions is high — and will only continue to grow. So, it’s important to understand the current market and set a realistic budget. For example, a full-stack developer has more experience than a front-end developer or a back-end developer, so they command a higher salary.

Web developer salaries range from $49,000 to $129,000 or more.

Establish what level of experience you need in a web developer, look at the local market, and budget accordingly.

Broaden your search

In addition to posting job openings on LinkedIn and job boards, share your web developer job listings on social media. Post on Facebook, Twitter, reddit, and even Mastodon. Word of mouth is a great way to attract IT talent.

Web developer hiring process

Web developers have applied for your open position, and you have reviewed their resumes. Now that you have a short list of candidates to interview, what next? Here are the potential stages of hiring a web developer, depending on your company’s needs.

Keep in mind that with the current demand for web developers, they are most likely interviewing for multiple roles. A speedy web developer interview process is one way to stand out from other companies. Consider combining some of the stages below if you can, like the aptitude test and the coding test.

Initial interview

The initial interview is often a phone call or video call with the hiring manager. This meeting is an opportunity for the hiring manager to learn more about the candidate’s skills, experience, and career interests.

If both parties feel that there is a potential fit, the hiring manager will then invite the candidate to the next stage of interviews.

Aptitude test

Some companies may require an expertise or skills test to be administered as a part of the hiring process. Aptitude tests measure cognitive skills, problem-solving abilities, and critical thinking skills.

Using aptitude tests during the hiring process is a great way to screen candidates based on their abilities. This can help overcome an unconscious bias for candidates who attended a certain school or worked at a prestigious company. Aptitude tests are also useful when recruiting entry-level web developers to assess their potential for success.

Technical coding test

Similarly, companies may require a technical coding test as part of the hiring process. Coding tests are pretty self-explanatory — they measure a candidate’s ability to code.

A technical coding test can combine both written questions and live coding exercises to assess the candidate’s knowledge in areas such as front-end development, back-end development, or database design. This test aims to see if the candidate has the necessary expertise required for the role.

Interview with the team

A team interview is a great way to include multiple stakeholders in the web developer hiring process. This is especially important if the hiring manager doesn’t have a technical background. When deciding to include in the team interview, think about who will work most closely with the web developer. Not only will they ask web developer questions specific to the role and upcoming projects, but they can also assess the candidate for culture fit.

Final interview

When hiring for a senior web developer or a technical director, it’s a good idea to have a final interview with senior leaders and executives. At this point, web developer interview questions will focus more on strategy and leadership, and less on specific technical skills.

Strategic Web Developer Interview Questions

Hard skills and soft skills are necessary to succeed in any role. For that reason, web developer interview questions can’t be limited to just technical experience. For an effective interview process, choose a few questions from each of these categories. Coordinate with any other interviewers to minimize too much overlap of questions.

  • technical interview questions
  • interview questions about company culture
  • personality interview questions
  • behavioral interview questions

Technical interview questions

These web developer interview questions are best asked by a technical director or another leader from the web development team. Not all of these questions will apply to every role, which is why it’s important for someone with web development experience to decide which questions to ask.
