Super Retail Group Project Manager interview questions

Saw advert on Linkedin & got in touch with the internal recruiter in mid Jan to express my interests & sent in my details. In mid February the internal recruiter got back to me and I managed to secure an interview at end Feb. The role was a 2 year fixed contract for a project manager working with the business and IT. I was provided a background on the program and then probed for my skills, experience and behaviour. Interview went well but I was told they had other candidates to see. In late March the internal recruiter came back indicating that I was the preferred candidate - I got very excited. When I asked if an offer was going to be made, further discussions had to be held internally. I then got a call from the internal recruiter indicating that although the program was going ahead, the go ahead had not been provided by senior management to fill the role. Disappointing that the role had not firstly been agreed by senior management before proceeding with interviews.
