Insight Global worked with the client company (across the US) to get an interview and offer within a day and half, given I already had an offer I was accepting in my area.
Not afraid of negotiating a good bump in rate for relocation comp.
Very workable around circumstances. They arranged for a drug test at a location out of state while I was on the road so that it would be done in time to start.
Cons
Higher rate due to relocation takes time to re-coup compared to upfront relocation reimbursement or signing bonus. Long-term, the higher rate ends up better anyway.
