"I always ask candidates two things," Fertitta tells CNBC. "'How many times have you been fired?' And, 'Do you watch your clock when it's time to go? Do you look at your phone? Do you look at your watch?'"
Nothing goes unnoticed to an employer, the billionaire emphasizes: "Everybody notices if you're the last one in in the morning and the first one to go in the evening. Always remember that as an employee."
This doesn't necessarily mean you should put in more hours just to put in hours. "When you have to stay late, you stay late, and when you don't have to stay late, you go home," Fertitta says. But, "you do whatever it takes to get the job done that day."
