Q1. Which programming languages do you know?
I know most of the common programming languages that a web developer should know, including:
- C++, etc.
Q2. What are the differences between http 2.0 and http 1.1? Which one do you prefer using?
I prefer using http 2.0 over http 1.1 because there are some really good advantages with http 2.0 when compared to http 1.1. The advantages are that http 2.0 supports queries multiplexing and headers compression. It also supports priority and more intelligent packet streaming management. As a result, it reduces latency. Http 2.0 also accelerates content downloading on most of the modernly developed web pages.
Q3. How do you reduce the page loading time?
Q4. What is CORS?
CORS, or Cross Origin Resource Sharing is the process by which the restricted URLs can be requested to be accessed by a different domain from the primary domain that was used to access the web page in the first place. Through the CORS mechanism, a browser and server interact between them to determine whether it is safe to allow the restricted resources or not.
Q5. What is a pseudo-class?
A pseudo-class is a style that is used to denote the state of an element of a web page. For example, when a user hovers the mouse pointer over an element in a web page, it can change the style, or the color of an embedded element, or the style of the links that are visited vs the links that are not yet visited.
Q6. What is an ETag?
An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned. (source: Wikipedia).
Q7. What are the new input types that are included in HTML5?
There are many input types supported in HTML5. Some of them are:
- number range
Q8. What is long polling?
Long polling is a web application development pattern. It is used for matching pushing data from the server to the client. By using the long polling pattern, when a request is sent to the server from the client, the connection remains intact until the server is ready to send the data to the client. And in long polling, the connection closes after the data is sent back to the client only. Or, connections can close when a timeout occurs.
Q8. What CMSs have you worked with?
A web developer needs to be acquainted with the common and popular types of CMSs or Content Management Systems. If you don’t know how to work with Content Management Systems, you need to update your skills as soon as possible.
I have worked with all major Content Management Systems like
- Cushy CMS
- Text Pattern
- Expression Engine
- Radiant CMS
Q9. What is the difference between HTML5 Canvas and SVG?
Q10. Tell us about your SQL/ Python/ HTML skills?
One of the web developer interview questions will probably be about these, or any other programming languages. So, revising the programming languages before attending an interview will help you to answer them. Remember to keep your answers short and concise. Do not elaborate too much, and mention only the most important points.
Tricky Web Developer Interview Questions and Answers
There will be some questions that are not directly related to the technical knowledge of web development. Rather, they are about yourself. See below to learn how to answer these questions.
Q1. What’s the best thing about being a web developer?
This can actually be a fun question for you to answer. If you have chosen the profession of web development, there must be at least some reasons that give you intense job satisfaction. Explain those reasons in a compact way, like you love the creativity that the job offers, or you love the fact that you can implement your technical knowledge every time in a unique way for each project, etc.
Q2. Have you ever been blamed for something you didn’t do? How did you react to such situations?
This is one of the trickiest web developer interview questions ever. On the one hand, you don’t want to answer with a simple NO, because that will be unimpressive. On the other hand, if you answer YES, it might sound that you are passive-aggressively blaming the previous recruiter. So, you need to be diplomatic while trying to answer this question.
Q3. How do you handle negative feedback from clients?
This is another of the common but tricky questions that is frequently asked in interviews. Answer this question with a positive approach.
Negative feedbacks are common in any creative job. I have experienced negative feedback from clients before. When I receive a negative comment on my work, I try to understand their perspective, and work my way to fix the problems and deliver what the client wants. It is my duty to provide the client exactly what he wants, no matter how many attempts or time it requires.
Q4. How do you incorporate client’s feedback into your work?
This is an extension of the previous comment. Elaborate on the above idea and let the recruiter know that even if you sometimes disagree with the client’s feedback, you try to meet all the expectations from the clients by changing and updating your work.
Q5. Do you consider yourself a good web developer? Why?
Yes. I believe I possess all the necessary hard and soft skills that are required to become a good web developer. Besides, my previous works have made both my bosses and my clients happy, and I have received praises and appraisals for my work in my previous company. So, I consider myself a good web developer.
