I have inquired about a PhD position at a group. After a chat with the supervisor, and some time, I was invited to apply to the doctoral school (they never said they'd take me). Then holidays came and afterwards, a message asking if I had sent yet the documents. My reply was no, that I let them know. Then many other many follow ups from them: they had secured funding, they would start soon to advertise the position, the summary of the advertisment, mentioning a new, earlier deadline for applying...
And now, them asking again if I have sent the documents. At this point I think it would be best to let them know that I will be sending them only when I am sure about committing to the project, and that I have other options to evaluate.
Do you think this is a good idea? In any case, do you have any advice for doing this "the right way"?
My message is: I consider this project, but I haven't made up my mind.
I needed references to formally apply for the programme. One of the professors that could write a letter for me, also offered to me a position (spontaneously). That's why I can't just submit the application.
