How Much Does Advisor Fit Matter When Choosing a Chemistry PhD Program?

[lucaswilliam678]

When comparing chemistry PhD programs, I think it can be difficult to look beyond university rankings and research reputation. Two universities might have strong chemistry departments, but the actual experience can depend a lot on the research group and the professor you end up working with.

I'm curious how much importance current PhD students and recent graduates would give to advisor compatibility when choosing a program. Research interests are obviously important, but things like communication with the PI, availability of funding, expectations around publications, and the working environment also seem to make a big difference.

For those who have already gone through this process, what helped you decide whether a particular research group was the right fit? Did you get a clear picture during interviews, or did you only understand the lab environment after joining? I'm especially interested in knowing which questions are worth asking current graduate students before making a final decision.
