I have such bad things to say about recruiters. They generally don’t have a clue about any of the skills related to the jobs I’m after, and they take a huge cut of the pay the entire time I’m working the job.
On the other hand, the two best jobs (highest pay and best working environment) I’ve had in my career, I got through recruiters, so I acknowledge them as a useful business when it works out. The last one has led to the company buying my contract and hiring me directly for the past 12 years
