So youve been screwed over twice

That really sucks OP. You should go back there and ask if you did anything wrong.

Seems like you're doing well so far. Keep at it OP, things will work out!

Hopefully whichever position they don't take will then be offered to you, as the obvious second choice.

Don't sweat it, keep grinding and you'll get your shot OP

Maybe you can contact the companies and ask them if your competitor rejected their offer (in a professional way), if they would consider you for the offer. And if they do accept you, I know it would suck thinking you are a second choice but once you get working you can do your best and show them what they would have missed out on!

That truly sucks, OP. But if you were neck and neck with the other guy, the job he doesn't choose, you should at least have the other job option...

I hate to tell you, but you were probably not neck and neck with another person. HR typically says that to everyone just to make you feel better in case it doesn't work with the other applicants.

Isn't it possible that someone was more qualified then you that was interviewing for those jobs. If this is your First time trying to get a job then you need to understand that sometime your going to have to go on many job interviews before you get a job. Good luck with the job search and don't be afraid to ask why they didn't hire you.
