I got the skype interview after the first round interview which is on the phone. And they are really professional, because during i was on skype interview there are two senior employee who may works at the same department of the job role I applied. I failed because I could not give them the best answer they want. And, at here I would like to share the question what they asked me, by the way the question is really easy, the best way to answer is being prepared well before the interview.
