I was referred by a friend first I received a call from HQ in Austin for first contact, then second call with HR in Dublin, writting test, interview with TL and assistant TL and finally interview with director all of this took more than 2 months process . I passed all the steps except the 4th step when I was interviewed by the TL and the assitant they put too much emphasys to know who I knew in the company because some of them were ex-colleagues they asked me twice in and after the interview. It looks from my experience it is not the first time I apply they balance more the friendship and networking in order to hire someone instead of the education and professionality.
