A quick trick I use to filter out the terrible ones is to ask them for a copy of the Job Description. Copy and paste it into Google you you find the job on a job board 🚩 (to me at least)
Another bad one but common (annoys me due to lack of trust all around) they ask for you to send a resume in Word format. In my experience they rip out your contact info and then send to potential employer. Why it annoys me is they generally pitch “I have a long relationship with the hiring manager” if that is true why do they not trust the hiring manager with your contact info?!?
All that said I more than 2x my salary working with recruiters but I did have to hold their feet to the fire multiple times.
