Job Update

I have no idea what is going on. Last Monday I was offered a job and told it may take a while to extensively check my background. I went in for my drug test on Wednesday and last Thursday they called and left a message for only 1 reference but have yet to actually speak with her.

I am getting aggravated. So much so I am going on an interview tomorrow with another organization. It's about half the pay but I'm annoyed enough to take it. I've said it before and I'll say it until I drop dead: HR people suck. They make the entire hiring process as horrible as possible. Am I really supposed to get excited about working somewhere when I am offered a job and then hear nothing from them? I don't even believe the offer.
