1st round:
Was asked Javascript questions, some CSS questions-pretty simple and straightforward.
2nd round:
Turned out to be my worst nightmare. Interviewer was snooty and just kept boasting about how good he was. Asked me most questions out of context related to BE, inspite of being aware I am not familiar with them and then kept mocking at me throughout the interview
3rd round:
I was asked regular Javascript and AngularJs questions.
Overall if you are looking for healthy working atmosphere among peers, then this is not the company for you.
