PTC interview questions

The interview took approx 4 weeks. Phone interview with recruitment consultant was very generic about what I did in my past life, about their company and that the recruitment process will be ... long and tedious. Second skype interview with a Director went also well and again it was generic enough and very simplistic. The 3rd one was with an internal expert and it was focused on a very specific area instead of being generic to see if the candidate was "good enough".
