(If you don’t know what that is, it’s a personality type and you can find out yours here.)
Introvert to an extrovert haha, although of course there’s more differences. It’s weird, because the INFJ personality type is more known to be extremely vulnerable/emotional/untrusting, etc and the ESFJ is seen as very outgoing/bubbly/affectionate/complimentary/open. I could go on, but the differences are pretty apparent. The importance of relationships and love is central to both types (although that can be said for pretty much everyone) so that’s one thing that didn’t change. It’s all just really interesting, I dunno.
If you take the test I would suggest using google to further research your profile type because the one on the test site is really weird, I must say.
