How to do FT recruiting

Let's say I'll be at a mid tier BB this summer with a non-target school background. I'm interested in transitioning to an EB for FT as I want to be in the classic advisory role. How do I go about interviewing for EBs during my SA stint. I've also heard that people get FT offers from their interviews before the end of the SA stint.

How do I communicate to my network at these EBs that I'm interested in FT recruiting. During my SA recruiting I built up decent networks at the EBs I wanted to be at. I don't want to raise any flags by looking to jump ship before I even start at my bank, but at the same time I don't want to miss FT recruiting, which from what I heard is significantly more informal and sometimes banks wouldn't even post an opening, people just know people who want the process and put them through the interviews
