Completely agree. We have a seminar that's supposed to happen every two weeks, but even with 5 PIs trying to fill the slots with random visitors, collaborators and some well-known people doing a tour of Europe, there's always space for more speakers.

I'd say you don't have to push it that far. In this case ANY amount of clear deliverables, timelines and meetings would help the project along faster.

And for your second comment: I made an edit, and I completely agree. Just calling them that you found another position (or not even calling and just not showing up...) would be absolutely unacceptable. Keep your supervisor in the loop.

For your first comment: this is what you should talk about, but the emphasis shouldn't be on finding out the negative impacts of your supervisor. Those are their problem, and although it would be good to keep it in mind and to try to mitigate the consequences, ultimately it's really not your responsibility as an applicant. I think asking implies too much something like asking for permission. The conversation should be about your plans, and if there are negative consequences reneging is still an option.
