Initial screen involved a conversation with HR. This was followed by a series of interviews (8) strung out over months. One of the interviewers was clearly not trained how to interview, otherwise everyone was professional. After the 7th interview I was told that I would be made an offer. The 8th 'interview' was to tell me that the position had been killed for the quarter due to budgetary decisions and that the would contact me the following FY. Have had interim follow up to that effect. Process really left me at a loss, although the hiring manager seems like a solid manager.
