I was invited to interview with a Senior Manager, then asked to immediately return to meet several other team members. This consisted of 4 additional days of interviews, for a total of 5 separate days of consecutive interviews because they were quite interested. Upon conclusion of the interviews however I was not contacted by anyone from the organization and had to make numerous follow up calls/emails regarding my candidacy. Finally I received an email back that another candidate was selected. Of course it's fine to select another candidate, but the professional way to handle would have been to make a call or send a more timely and detailed email given the process I was asked to participate in and the time I spent there.
