<human>: When I am out with friends or family I have a really goofy and bubbly personality. However I have noticed that when I go to interviews or talk to college professors for example I put on this "professional face" as I call it. Basically I become very serious, talk slower, and think about what I am saying a lot more and I do so without even realizing it. 

I think this stems off of my dad being a police officer and if you have ever been with a cop both on duty and off you see how different they act in their work environment. When I used to go to the station or hear him on the phone for work I saw him becoming very serious and professional and I think I may have picked up that trait because of him. 

Is that a good thing? I know they say to be yourself at an interview but I find it hard to not put on this professional face of mine and I was wondering if anyone else does it too.

<bot>: When at interviews I turn into a more serious and professional version of myself and very few of my actual personality traits show in doing so. Is that a good thing?
