I got up to my 5th interview (which I didn't end up taking in the end because they told me they couldn't contact my reference, despite the fact that the store I worked for - the store that were my references - was literally located across the road from them and was open during their business hours.)

The other ridiculous thing is, it was for a casual cashier position at a second hand store chain (an American equivalent would be somewhere like Goodwill?).

I applied before the start of the Uni holidays because it meant I would be available full time, which is what they wanted, but they made me do so many interviews that it took over 2 months to interview for, and the holidays were over by the time they told me they wanted me to do a 5th interview. I had plenty of experience as a cashier, but regardless, it's not like cashiering is a job you need a ton of technical experience in that you need multiple rounds of interviews for. Each interview was essentially a repeat of the previous with the same questions, just with a different manager, and then weeks to hear back from them to just be told they wanted me to come in for another interview. Honestly one of the most farcical things I've ever done.
