PPD Senior Executive Assistant interview questions

Applied though PPD website. HR contacted me for a pre-screening and then sent me an application to complete. I had to wait a few weeks for all of the players to be available. They rescheduled twice. Once we confirmed, I interviewed with an HR representative and a current senior executive assistant. Once that was over, I met with the VP of HR. Interview questions were typical and both women we very kind and easy to speak with. Interview was very casual. The negative impressions were with the expectations. I was asked if I could be available at 6am to arrange meetings and if I was available to answer e-mails up to 10pm. The current senior executive assistant said her hours were so long that she had to have extended day care....for her animals. Even after that strange exchange, I was willing to put in the hard work and hours. About a week later the HR rep called to tell me that they had decided to go with someone else. A friend of mine (an employee of PPD) later revealed to me that they hired someone from within. A complete waste of my time.
