I applied at the agency for the position of an intern (Account management) through email, and was invited for an interview shortly after (I was located in Germany and flew to Dubai for an interview!). I was interviewed by the Account Director on the Brand team I was initially supposed to work at. The interview went smoothly and ended quite positive, even with a definite "yes". A few weeks later, after not hearing from the agency, I got in contact again, turned out that the former HR Manager and Account Director who interviewed me left the agency, so I was pretty lost and scared that the granted position was void. Fortunately the new MD picked up my case and made sure i was assigned to a team and were clear about the rest.
