Am I blacklisted or something?

Another rejection letter arrived today.

I applied to the new Tesco store opening locally. Today I get a rejection letter which means I got rejected more or less straight away. So I'm not even fit to stack shelves.

I'm now beginning to think I'm on some sort of "don't employ him at any costs" list. I mean, I've had job offers, only to have them withdrawn the next day with a variety of reasons, which is kinda freaky. I've had temp jobs that have supposedly been a shoe-in to a permanent job, then I've also been given all sorts of reasons why the job hasn't become permanent. Always its m=not me, there's some other reason.

I know there must be humdreds of applications for jobs so employers can pick and chose, but the volume of job applications I'm making should bear some fruit, the law of averages says that you should hit the jackpot sometime. The lack of interest and the other related things means I really can't help getting suspicious now.
