1st Round Hacker Earth ,multiple choice question with few subjective i.e define some thing with example (not on programming). 2nd Round same question of Hacker Earth now with pen paper.Might be they don't believe on candidate.3rd Round Technical F-F.It's again you feel like pen per round as they have similar type question ready.they will ask to write o/p of each problem.Very few theoretical question.Most of the question were based on prototype,"this",class concept in js.CSS and HTML question were almost 1 or 2.Those who are going for interview clear your concept of "this" if you don't know.
