- Well being of the employee completely ignored: client at all cost! You could be a willing and hard working consultant, your interest will never prime. You could give it all until it impacts your physical and mental health, but would get nothing in return (career and interests wise). I have never seen so many burnouts and sick leaves across all the companies I was in my career.
- They will not put you in mission where you do not have an expertise. Hence, if you do not already have various skills and knowledge, they will most likely trap you into a mission, just to bill, even if you do not like it and it does not fit you.
- Linked to the above: very hard to learn new knowledge. If intellectual curiosity is what you seek, look elsewhere.
- Management/HR with unappropriate behavior (strongly related to the above-mentioned points).
