3 months
I've been working at the same place for 3 months now. And I absolutely LOVE my job still. I don't think that's going to change. I am definitely doing really well at work, they've even given me a project (which if you know anything about where I work you know that's a big deal for my 'type' of employee to have).
Anyway, I work for a rockin' company and my job is kick ass! w00t!!!!
