The Antra hr called for around 20mins, pretty easy. They asked about your resume and your career goal and would talk about their company and the whole process. Nothing technical. And then they would arrange the second interview for you, which is the technical.

The first round of interview would ask you some basic questions on javascript and front end technology, while the second round of interview would ask you to build a program followed by an interview asking about what your thought process is when building the program.
