The hiring committee is not the last step, you need to get accepted by the SVP of your org and the site lead as well, both of them are single persons who can torpedo your application alone.
Yep, I made it through the hiring committee and got denied at the SVP level. Was fun getting a literal congrats from the recruiter, then meeting my future team that gave me the thumbs up, then getting a call that it wasn’t going to happen... rough rollercoaster
