Web Developer Interview Process

When preparing for an interview as a Web Developer, you can anticipate that the interview will occur in 3 Phases:

  • Screening
  • Phone or Video Interview
  • Onsite Interview

Each of these will involve various types of questions and some hands-on exercises.

Screening in Response to a Referral or Online Application

The initial screening is used to validate your resume and learn more about your experience, skills and background. You may also be asked about your salary expectations, availability and other employment-related issues. Finally, they will discuss the next step in the process and offer to answer any questions you may have. This takes about 15-30 minutes.

Onsite Interview

The onsite interview is the last phase of the interview process. This involves meeting with one or more contacts from different parts of the prospective organization. The people you interview with may include HR representatives, the Hiring Manager, Managers from other departments such as Quality, Product, Operations, Finance, and Sales, and possibly other Web Developers who are members of the team you will be working on. Onsite interviews can last from a few hours to over several days, depending on the organization and the type of job you are interviewing for. You are likely to be asked a wide range of questions from every category. These include:

Technical Phone or Video Interview

The next step in the process is a phone or video interview. This will be more in-depth than the initial screening and explores your qualifications more extensively. This part of the interview will include several different types of questions. These include general, technical, and operational. The purpose of these questions is to explore your web development skills and experience in more detail. You may also be asked to solve a web design or development challenge, either in real-time or as a take-home exercise. Usually, the interviewer will allow you to do the exercise in a language you are comfortable programming in. The phone or video interview will take from 1-2 hours, depending on whether there is a live development requirement.

Being prepared for these types of questions and practicing your responses before the interview will help you to be ready to respond to them during the onsite phase of the interview process.

  • Situational - Situational questions are similar to behavioral ones, except they create future scenarios to discover your methods for resolving issues. This requires you to project what you would do when confronted with a situation described by the intervi
  • Cultural- These questions help the interviewer determine how well you will fit into the organization and contribute to its culture or conflict with it. Questions will explore your work style, preferences, ability to collaborate and other personal traits.

The interview typically concludes with either an immediate job offer or a brief description of how the overall interview process is being conducted and when you can expect to hear about the organization's decision. Additional steps in the process may include asking you to provide references the employer can contact or participating in online or live tests to determine your personality type, such as Myers-Briggs.
