Bad Credit Checking

What Happens If The Navy Sees I Have Bad Credit When Checking For My Security Clearance? Do I Have To Choose From Another Job Or Just Be Placed Into One That I Have No Choice Over??? Somebody Please Let Me Know What To Expect I Have No Criminal Record But I Know There Is Credit Checks And I Know My Credit Is Not Good At All.
Okay And If They Sit Me Down And Ask Me To Explain Can I Still Get The Job Possibly Or Does That Step Already Mean Its Not Happening?
