For my own sanity I'm trying to limit the number of companies I'm currently interviewing with to 3. If I get an offer or a rejection from one, and if time allows, I'll apply to yet another I'm interested in.
If I'm already interviewing with three companies, and I get contacted by recruiter B from another company I'm interested in, what's the best way to handle that?
I hesitate to be frank about what I'm doing because it seems like that would suggest to recruiter B that they're a second choice. But do they actually care? What is the best way to respond?
