I have been offered a postdoc position in a very good university.
However, I had a quite negative impression from the PI, who looked a bit bossy. Also, I had the sensation that he is looking more for a manger of his phd students (who btw have a better CV than me) rather than for a researcher.
Given these doubts, I would like to contact a previous postdoc of this professor, to have a feedback on his experience.
Is this a bad idea? Or is it something common?
