I applied through a recruiter. The process took 2 days.

There were two rounds and both were in CodeSignal. They were mainly focused on JavaScript problem solving and a bit of CSS and AngularJS. Some questions were also based on data structures. The first interview was with the manager. He asked some great JS based questions. He had a good attitude and was able to guide me in between. I got to learn a lot about my own understanding of JS after this interview.

The second interview was with another developer. He was really rude. Even after giving a proper solution, he wanted me to implement the solution using his approach which I think was more complex and time consuming. But he kept on insisting on following his approach. Also, it felt like he was mocking me/my current company for some of the work that we do or the approach that we follow. He needs to understand that different companies have different people and different priorities. It's not necessary that whatever he is thinking the same thing the other person is thinking. I felt he was only interested in himself and his way of coding.

The interview included questions based on prototypes, implementing a polyfill for bind, data structure questions based on trees, components in AngularJS, and closures in JavaScript.
