Byron is correct.
I got a DUI in CS, and I had no problem getting offers and finding a good job.
Now, if you have a ton of other stuff....But nah, most people won't care about DUI.
One word though, DUI in Texas is different from DUI elsewhere. When people in NY, FL and all the other states hear DUI, it is driving while drunk, the equivalent of DWI in Texas. DUI is a much smaller offense in Texas, and that fact may need to be explained to someone who is unfamiliar with Texas Laws.
