Nothing happened... that's the problem.
Unwilling or unable to articulate usable feedback. I have my family counting on me and I get jerked around.
Either by company culture or operating principles not in favor of the "client", Robert Half is a very poor choice when it comes to building the career you've worked so hard to build.
If I wanted to get screwed over any worse I would have to put my future in the hands of my blood thirsty Ex.
So head warning from my example. These people will not do a single task outside their scant job description despite how easy or helpful they know it will be.
Product or Service Mentioned: Robert Half Recruitment.
Reason of review: Poor customer service.
