my zoom account vs hitting a link from a company Im interviewing with today

I've got an interview today.  They have sent me a zoom link.  I have to have a virtual background bc I live in a small apartment.  While I've opened a zoom account and put a virtual background on.

Will this background come on when I hit the link for the interview?  I was told to only hit the link when I'm ready to start the interview so I will have no time to hit the filter button prior for that call.

I need to know now so I can start moving furniture to have a blank wall 

Thank you
