"First time caught" is a lie. You were also caught the previous summer on the same road. And didn't learn a lesson.
Not momentary. Getting caught twice in a year is a clear demonstration of repetitive behavior. It's like drunk driving. Almost no one gets caught their first time. And you got caught and still didn't modify your behavior. Must be behaving worse, actually, cause no one is giving you a warning for 30 over the limit. So you got a warning and decided to go faster.
And, finally, the truth comes out. He's a lead foot and using youth as a mitigating factor.
As others have pointed out. This isn't likely to change your career path. But it probably should. You seem clearly happy to shade the truth about how you drive, how often you have been caught and think that being young is an reasonable excuse. Or, worse, think that you should be able to go to the hiring manager and say, "hey man, I drive like a crazy person but it's fine because I compartmentalize and I would never dream of doing something unsafe in a plane."
