None. My Phone interview was pretty straight forward. In the end, it was complete waste of my time.It is one of those companies whom I thought were unprofessional and not completely honest during the interview process. On site interview was twice postponed by the HR citing difficulty in scheduling. If you are not interested, then just let the candidate/s know rather than wasting their time. This interview was a great disappointment. I have NEVER experience a company that has such a poor process
