I have been working at FINRA full-time
You can't beat the mission here at FINRA
Like many companies, we do suffer from the occasional clique or groupthink
I applied online. I interviewed at FINRA (Rockville, MD) in August 2017.
Had a phone call with interviewer - pretty easy, just glossing over resume. They invited me in to meet the manager and director - nothing but STAR/situational/behavioral questions. They invited me back one more time to meet the senior director - again all STAR questions. Received an offer the following week.
