Less recruiter and more recruiting company.
Specifially: Robert Half.

t;ldr version:
Robert Half is scammy as hell, and they 'fired' me for quitting when my girlfriend got raped. Really.

------

Robert Half took half of my paychecks for the entire duration of my contracts with them. I didn't know right away because, as a policy, they hide how much the hiring company is paying for you, and they also forbid the company from telling you. (The company pays RHI, RHI pays you). Makes sense why they hide it because it certainly pissed me off.

Long story short, I worked for a php dev shop through them (after telling them to lower their fees or i'd walk), worked there for awhile (while remote moonlighting because why not!), and quit. I quit because my girlfriend at the time had just gotten raped, and with the emotionall fallout from that, there was no way I could focus on two jobs and be there for her. My boss understood and let me leave, though it put him in a bind.

The next day, I got a call from the regional manager of Robert Half. He was a total tool. He demanded to know if I quit, didn't care why I quit, proceeded to "educate" me in the finer points of why that was unprofessional and why i'm unemployable, accused me of lying about idr what, and finally switched into legalese to say "I regret to inform you that you can no longer consider Robert Half as a means of employment." (or something along those lines) and hung up on me. Asshole. I hope various large someones rape him so he has an inkling what it's like to be objectified and thrown away like trash.

Guy was an asshole; probably still is.
RHI was awful and scammy; probably still is, too.
Wasn't really a fan of the job either.

So at the end of it, I wasn't out anything but some patience and serenity (a lot of serenity). I kept the first (remote) job, was there for my girlfriend, and helped her through everything.

But yeah, Robert Half?
They can fucking go to hell.

Dumbest project for me was separating a company into four different companies (four different phone systems) because they were under legal fire.

They wanted it separated but still function the same. There is still the possibility that the companies will merge back together.

Those. Fucking. Asshats.
