What steps do you take to vet a prospective therapist for adequacy?

The past several years I've bounced from therapist to therapist after my first ever therapist had to move away and i chose not to go virtual with her, but I've had trouble finding someone competent.

Most of the ones I've found in the last few years do not wish to ask me the tough questions needed for me to grow beyond what my own introspection can do. Because of this and other various problems like them seeming uninterested or overly talkative about their own life, what do you do to vet a new therapist for long term sessions moving forwards?
