Diageo Screening Interview interview questions

Applied Online, Recruiter emailed me to setup interview. On the day of interview, just minutes before interview another email says, "last minute change, interview rescheduled for X date, Y time.". The X date and Y time, was expecting the call and didn't call me. Emailed them, in reply "they asked for same day different time". No call yet. One of the worst interviews so far in my career. Waste of time.
