VSS Monitoring Engineer interview questions

Complete chaos with the interview process. Was contacted by 3-4 different HR people during the process and everything was disjointed. Seems that there was no continuity. Process took 10 weeks and I was not offered the position. I am not upset at not receiving the offer (that is life sometimes), but they way this company "jerks you around" and has you come in to the office 3 times and after that, long silence (no feedbaack) after the interviews.
