Technical Skills & Experience

• 6. Can you explain the difference between HTML and CSS?
  Answer: HTML is used to create the structure and content of a webpage, while CSS is used to style and format the webpage. In simpler terms, HTML is the skeleton, and CSS is the skin of a webpage.
  
  
• 7. What is a CSS preprocessor? How does it differ from CSS?
  Answer: A CSS preprocessor is a scripting language that extends the capabilities of CSS by allowing variables, mixins, and functions to be used. This makes writing and maintaining CSS code more efficient and organized.
  
  
• 8. Can you explain the box model in CSS?
  Answer: The box model is the way in which CSS calculates the size of an element. It includes the element's content, padding, border, and margin. This can be modified using the CSS properties 'width', 'height', 'padding', 'border', and 'margin'.
  
  
• 9. How do you optimize website performance?
  Answer: To optimize website performance, I use techniques such as minification of code and image optimization to reduce the page load time. Additionally, I also use browser caching and CDN services to improve website speed.
  
  
• 10. Can you explain the difference between cookies, local storage, and session storage?
  Answer: Cookies are small pieces of data stored on the client-side, while local storage and session storage are storage options provided by HTML5 for web applications. Local storage and session storage are specific to the domain that created them and do not get sent to the server with each request like cookies do. Local storage is persistent, meaning the data stays even after the browser is closed, while session storage is cleared once the browser is closed.
  
  

Behavioral Questions

• 11. Tell us about a time when you encountered a difficult project and how you overcame it.
  Answer: During my internship, I was assigned to a project with a strict deadline and complex requirements. To overcome this, I set up a clear project plan with realistic timelines and regularly communicated with my team to stay on track. I also broke down the tasks into smaller chunks and delegated some of the work to my team members, which helped us meet the deadline successfully.
  
  
• 12. How do you handle conflicts with team members while working on a project?
  Answer: I believe in resolving conflicts through effective communication and understanding. I always make an effort to listen to everyone's perspective and find a solution that works best for the team and the project at hand.
  
  
• 13. Can you tell us about a situation where you had to quickly learn a new programming language or technology?
  Answer: While working on a project for a client, I was required to use a specific JavaScript framework that I had never used before. To quickly learn the framework, I consulted online resources, took an online course, and sought help from my senior colleagues. This helped me successfully implement the technology on the project.
  
  
• 14. How do you handle criticism or feedback on your work?
  Answer: I see constructive criticism and feedback as an opportunity to improve and grow, so I always take it positively. I analyze the feedback, understand the areas for improvement, and work towards implementing them in my future projects.
  
  
• 15. Can you give an example of a time when you had to explain a technical concept to a non-technical person?
  Answer: While working on a project, I had to present the technical details and progress to a client who did not have a technical background. To effectively communicate, I used visual aids and simplified the technical jargon to make it easier for them to understand.
  
  

Situational Questions

• 16. What would you do if a website you developed had a major bug that needed immediate fixing?
  Answer: If a website I developed had a major bug, I would identify the root cause by debugging and testing the code. If the bug was urgent, I would inform my team to work on a solution immediately while also communicating with the client to manage expectations. I would also work on implementing a long-term fix to prevent similar issues in the future.
  
  
• 17. How would you handle a client who keeps changing their requirements for a project?
  Answer: In such a situation, I would first communicate with the client to understand their reasons for changing the requirements. Then, I would assess the changes and the impact they would have on the project timeline and deliverables. If the changes are feasible and within the project scope, I would work with my team to accommodate them. Otherwise, I would discuss alternatives with the client or suggest modifications to the original requirements.
  
  
• 18. How do you approach testing during the web development process?
  Answer: I believe in conducting testing throughout the development process rather than waiting until the end. This allows me to identify and fix any bugs or issues sooner, saving time and ensuring a better end product. I also use a combination of manual and automated testing to ensure thorough and efficient testing.
  
  
• 19. How would you handle a situation where your team members are not meeting project deadlines?
  Answer: I would first try to understand the reasons for the delay and offer support to my team members to finish their tasks on time. If the deadlines are not being met due to external factors, I would communicate this to our project manager and discuss any necessary adjustments to the timeline. If the delays are due to a lack of effort or commitment, I would communicate my concerns with the team and try to find a solution together.
  
  
• 20. What would you do if a client is not happy with the final product and wants changes after the project is complete?
  Answer: In such a situation, I would first communicate with the client to understand their reasons for being unhappy and assess the changes they want. If the changes are minor and do not require significant resources or time, I would work with my team to accommodate them. If the changes are significant, I would negotiate with the client to discuss a new project for the changes requested.
