Applied to a job at the Phone Store at my local Tesco for a permanent position. Was offered an interview, which I assumed was for this position as it was the only role I applied to. Showed up to the interview only to find out it was a group interview for a different position (Christmas temp role for the grocery store). I was not informed of either of these things in advance, and had I been told I would not have bothered as I am only looking for a permanent role. Totally forgot about this as I wasn’t interested in the role they interviewed me for, and I thought maybe they would be confused if interviewing for both but I was still in consideration for a permanent role. A few weeks later I got an offer for a temp role that I declined.
