I was called for a f2f technical interview.There were two people on interview panel one was tech lead I guess and another was hr.Only the first asked me questions related to Adv JavaScript.Initially He gave me a paper to solve which had about 10 code snippet all very logically set and very confusing. After that he asked me about 10 question I answered every single question . Question was based on closure,inheritance in JavaScript(scenario based), difference between null and undefined in JavaScript,arrays behaviour in JavaScript,javascript expression and some basic JavaScript which I don't remember exactly.After that he said me to wait outside .I was very sure that I was through this round but suddenly that interviewer came and said for now you can leave,HR will call you for the results. After that neither I got a single call from them.I tried reaching the hr who scheduled my interview through mail to atleast give me a honest feedback but he never cared to reply.I am not a fresher that I desperately need a job but they should atleast care to give a proper feedback .
