That's a relief. I thought you might be having a problem with an intermittent p*rn server or something......
I assume you would have to move for any of the jobs? Nothing really says you can't take the first job while you wait for the other two. I imagine they are going to run an extensive investigation on you for the first two and that can take over six months. Learn as much as you can in the interviews and then keep your options open as long as possible. Take the first job if you like it and wait for the other offers. Moving complicates the choices but you can't turn down a job you might like b/c you "may" get a job that you would like better.
