Calls. Everyone wants to talk or even video chat. It’s the most annoying thing, not only by recruiters; everything is a voice/video meeting nowadays instead of mail or text.
5 seconds with a search engine and I can usually find the exact job. Now I know the name of the company you're so carefully trying to avoid naming.
You're not going to take a call from someone you couldn't imagine working for.
The initial intro and description can be handled via email or text. If not, well that is a red flag right away.
