HCI is just like any other consulting firm except they pay the worst and you must complete at least 80 hours to receive the $12/hr "kicker" that would still equal less than the average payer.
Most of the consultants hired are not experienced, knowledgeable, have any clinical/IT background, or professional.
Since most of the consultants are not professionals, the employees are micromanaged and results in a stressful work environment.
HCI also provides the worst accommodations for hotel and transportation. The hotels are cheap and most consultants have to share car rentals.
