Massive turnover in recent months. Almost like an exodus.
Overtime is the norm. Don't bother complaining about it. You'll just get shot down and it will affect your overall feedback.
Horrible management team that ignores clear signs of failure and ignores feedback from the people getting the work done.
Weekend and holiday work is demanded, not expected.
Poorly resourced projects with only a handful of people doing an unprecedented amount of work.
Lack of care for employee health as long as client gets what they want(Which they never do anyways)
Overly ambitious deadlines that they know can't be met.
