* I am assuming you are applying/interviewing for developer jobs.

Stop worrying about being "too bubbly or enthusiastic", coming across young & organizing meetups.

Start worrying about not having outside work projects & being weak on technical questions.

You need to be able to prove to a potential employer that you can do the job. Organizing meetups is nice but does not show anything about your development skills. A github profile with a few projects related to the type of development you want to get into will do much more for you than anything else.
