No, i don't think they need to be perfect or comfy in one day. But i do think you should get a good feeling about them, a sense of who they are and how they work, you should feel a draw to them and like you're excited to work with them.

I think a good sign is if they are also thoughtful, willing to negotiate things like boundaries, see the therapy process as collaborative etc. I don't think any T is literally "perfect" i just mean as close a match to you as possible.

Also i wanted to say about speaking to them about boundaries. Are you painting a picture that you have lots of difficulties with boundaries? It's good to be really honest but not overly negative about your difficulties. Cos as soon as any new T hears that, alarm bells ring and they seem to overstate how boundaried they are, and they can seem a bit rigid and actually when they get to know you and see that you're not really boundary-less they relax them a bit. That's been my experience. They start with the walls quite high, keep to the traditional boundaries, but as they warm to you and trust starts to build between you they can bring them down a bit and work with you about outside contact.
