Post-MBA Associate looking to lateral here.
Through a very senior level former employee of a bank, I was able to get in touch with a senior level current employee of the M&A group. The discussion with him went well and he said if/when they hire he'll let me know and keep me in mind.
I just found an opening in another group at the firm that I'm interested in. I'd like to ask him for a recommendation or introduction, but I also don't want him to be like "wait I thought you wanted to work in my group?" Then again if he's supportive it will have a lot of weight because of how I got in touch with him and his seniority.
What should I do? Try to find a different inroad into the group that's hiring? I did work on a deal during my MBA internship that they also apparently worked on, though I don't know who in their group worked on it or how to find that out. I suppose I could start cold emailing people I find on LinkedIn (unfortunately can't find any other connection to this group other than that one deal - no school or social connections to anyone).
Or should I say something to this guy along the lines of "your group is my first choice but I saw the other was hiring and I'm really interested in it"?
