Remember you are still in the interview process of the job.
Metro Tech is where all the big bosses are at. So why would you dress like you going to a ballgame ?
you don't have to go in a suit, but go in as you would a job interview a pair of slack/ or Jeans, but shoes and a decent shirt.
Be looked upon as a serious and respectful future member of the FDNY EMS dept.
Metro Tech houses the big bosses and trust me they notice things like your seriousness in your attire coming in for your future job.
just food for thought. ( FYI when I went to Metro Tech for ID and paperwork day I was thanked for showing up in proper attire for the JOB INTERVIEW PROCESS all I wore was a pair of slacks, shoes and shirt and sweater).
Appearance speaks volumes.
