I hear that it's common to talk with previous lab members before accepting a postdoc position.
I was wandering what is the best way to approach these conversations.
Should I let the professor know that I am going to email their previous lab members? I don't think they would oppose, and if they do that would be very suspicious. But I'm not sure if it's common courtesy to let them know, or if it's unnecessary.
Also, when I email previous lab members, is there anything I should keep in mind?
