Will alcohol fail a pre-employment drug test?

I'm curious about the potential effects of alcohol consumption on pre-employment drug tests. Could you explain if and how alcohol could potentially lead to a failed test? Are there any specific types of drug tests that are more sensitive to alcohol than others? And what's the general timeframe after consuming alcohol that it might still be detectable in a drug test? I'm interested in understanding the science behind this, so any insights you can provide would be greatly appreciated.
