Skype Senior Software Development Engineer interview questions

In total it took around 2 months from first interview to job offer. 2 interviews with HR 6 interviews with team I was supposed to be working with (which did not happen due to some management decision, so I effectively worked in another team, on different area than initially planned) 1 interview with mumbling manager, with so strong non-English accent, that it was not possible to understand half of all the questions. 1 background check
