PayPal Engineering Project Manager interview questions

Too many interviews: 1 telephonic, 3 days face-to-face each about 4-5 hours. Many interviewers constantly not available, seemed like scheduling was difficult / inefficient. due to work from home options. Everybody asked pretty much same questions - was difficult to keep up the enthusiasm going for that long; seemed like they were incapable of making a group decision. Also, felt like they already had pre-selected candidates - were just going through the process for legal.
