I upvoted you because parts of that are absolutely always true. Some of it depends on the type of consulting contract, though. Some of them call for a dedicated team of X headcount for Y time, and if the consultancy subs people in and out of that team without sufficient cause that's a big red flag.

Good point. There's a whole bigger world of contracting that I never saw.

I should be absolutely clear that my experience has been in small contract engineering firms. All of them were less than 20 engineers total and large projects were 3 engineers at any one time.
