EF (Education First) Program Support Manager (HSEY) interview questions

This was a HIDEOUS interview process-- It seems that there is no HR department in this company, as the person I was primarily communicating with is a director. There was a LOT of time (more than a week) between emails I sent and their responses; the process spanned from April to the end of August. I met with 4 different people in person (traveled to the office multiple times), talked to multiple employees via Skype and phone--the director doing the hiring didn't follow up with about the job for 2 weeks. TL;DR they strung me along for 3+ months, bouncing me around from department to department, no job offer.
