I am currently doing an internship/writing my master at a research institute where I have recently applied for a PhD scholarship. In order to apply for the scholarship I had to contact a some of my former professors in order to get some recommendation letter. I contacted professor X who wrote me a nice recommendation letter.
Two days ago I received a mail from professor X to me and all my classmates which contained a job offer. The offer seems very cool, and I would love to have that job, given that I do not get the PhD-scholarship.
Since it is not sure that I will get the scholarship I want to contact professor X saying I am very interested.
My question is how to write him. He knows perfectly that I have applied for the scholarship. Should I tell him that I'm interested if I do not get the scholarship? Should I not mention my priority, i. e. PhD over working for professor X?
