I reached out to my ex-supervisor regarding the availability of a RA in their group about 2 months ago, via mail. The email exchange we have had till now has been at 2:1; where I send a reply followed by a follow-up/reminder mail after 3-4 weeks. We have had 2 exchanges till now. In our last conversation through mail, the Prof told me about the availability of a position which is of my interest. They said that the description of the role will become clearer in a week. I replied right away, showing my keen interest in that position.
Now, it has been over 2 weeks since the time the vacancy's description would have been defined; as per the Prof. I am wondering if I should send another mail asking about the specifics of the role and how I can apply to the position. Would it be rude to send another mail because up until now I have only received a reply after sending a follow-up/reminder mail? I am in a dilemma, since it is a really interesting project to work on.
