Outsourced staff aug contractors have always been mediocre.

From the contracting side, I’ve worked as a staff Aug contractor for six weeks when I was between jobs in 2012 and it was so bad I just walked off with no job lined up within four weeks.

For context staff Aug vs consulting is about who owns the project

Consulting = the customer gives you high level requirements and statement of work and you control the project (or your company)

Staff Aug = the client controls the project and you are a warm disposable body.
