Yes I'm interviewing too. I've only tried one therapist, one psychiatrist so far. I'm with you though: I think I like the therapist, even pretty much, but he did seem all over the place. I'm telling myself that they're interviewing to be your therapist too. They wouldn't see you if they didn't want more clients and of course they want compatible clients. The point is your therapist may be nervous too even if he's very experienced. I would try him again if time and money/insurance permit.

Also I just can't help asking: does your therapist really tell you where to sit? That seems awfully controlling. Why doesn't he have just one place to sit then? And if he's playing games then he should let you choose and then analyze the reason you picked which place.
Is this really a thing?
