https://www.16personalities.com/personality-types is a pretty good (and free) resource to get started in this field.

There's a lot of sources out there on this topic, but Psychology Junkie is way better than I would have expected from the name. Two articles that mention these traits:

INFJ: https://www.psychologyjunkie.com/understanding-infj-intuitio...

INFP: https://www.psychologyjunkie.com/the-infp/

Thanks, I appreciate the links.

I happen to be in a new leadership role and in the middle of a hiring decision.
