My question involves criminal law for the state of: CA

I was pulled over 8/7 (exactly a week) for a DUI. (let me not get into that thought lol)

I turned in my resume for a job on that Friday 8/6, and then followed up that Wednesday which I received an offer for a interview. I went to the interview on 8/12 and today 8/13 got offered one of 3 jobs with the company. I have security clearance with NASA, and never have been arested prior to this. Heck I only have been citated for moving violation at a photo light which I took driving school several years ago, and a fix it ticket, and a seat belt (non moving, and another non moving for a cell phone ticket. That's in the past 5 years. I've never been in trouble before.

The employer called me and told me they where going to start my background check right now. So as I sit here of course eating away at the fact that I may not get this job(which I really really want) I'm looking for a answer to stop my mind or let me have some education on what might happen. The job however is for a company that handles HR for companies across the country, from there HR, I9's, to even background checks. So any answers are greatly appreciated. Advise etc...

Thank you!
