Sure? Went on a snowboard weekend getaway once, instructor recommended a beer as a class in the bottle because then you are relaxes. But just one beer. Since you probably interview no more than couple of times a year on average, don't see anything problematic. Now if you found yourself relying on liquid courage in your daily life, you would want to make some adjustments. If you are looking to relax a bit without impaired judgement or calories, try Kava instead of alcohol for example.
