Pros
With Harnham for almost 2 years as a contract employee. Hiring process was very easy. Was approached on LinkedIn, had a phone interview with the recruiter, then a phone and onsite interview with the contracting organization. Time from contact to hire was 3 weeks. My recruiter secured a higher hourly rate for me than my initial ask, which was in their best interest, but was a welcome bonus. Recruiter remains my main contact at the organization, and has always been easy to deal with, helpful as can be. They offer some benefits to contractors. The health insurance is super expensive and I skipped it. They offer a 4% match without vesting as long as you contribute at least that much - which was completely unexpected. There is also another match that is vested over time, but you'd need to work there for a handful of years to benefit.
Cons
Expensive health insurance, with no HSA option
