M-U-C-H too broad a question.

This is not a question that can be answered by this site. Whether you are hired or not, is entirely up to any prosepective employer you apply to.
A conviction for felony larceny can prevent getting into many colleges and will show up in background checks for jobs. The teenage conviction can be sealed or expunged in some states.
A misdemeanor of public intoxication could prevent a person from getting a job in Tennessee. The choice to overlook the charge depends on the policy of the company.

Firefighter

That's the problem. If you don't declare your record you can be terminated when/if the employer finds out. If you DO declare your record, you probably won't get the job. That's motivation for most people to stay away from crime.
