I got a call from HR via my profile from a job portal. After getting my availability and interest, they stayed in continuous contact with me. The interview was started on time and ended after 30 minutes. It was a video calling round via their hiring app.

It was my first UI interview experience, and I was not prepared much.

I didn't find many interview questions other than basic UI questions. So I'm posting a few questions. I hope this will help others prepare well for their interviews.

1. Tell me about yourself.

2. Question regarding technologies in previous and current projects.

3. What are Sass and Less?

4. Difference between JavaScript and ES6.

5. Difference between AngularJS and ReactJS.

6. How is AngularJS different from JavaScript?

7. Why use arrow functions (=>)?

8. How to set an image to its max height and width without stretching the actual image dimensions (without using width: 100% and height: 100%)?

9. What are the steps required to optimize a web application that is having multiple images?
