I have been applying for graduate level positions at several labs in the US, and I received the following reply from the PI of one of the labs I applied to - "if you are interested you should provide two or three references who are willing to write letters of recommendation for you, and we should then also schedule a Zoom interview."
What does providing references exactly mean? Should I just include the name, details and email of my referees and send it via email to the potential supervisor, who would in turn contact them for the recommendations or should I email the people on my list of referees and ask them to drop an email with my letter of recommendation to the potential supervisor's email?
I am confused. Please let me know what is the norm in academia and how should I proceed.
