Ineffective mentoring system (mostly works to reinforce the negative aspects of the culture and can backfire during your own appraisals)
Appraisal system places more emphasis on negative experiences/skills to improve, while down-playing or ignoring positive ones (i.e., the bad was awful, while the good was an outlier)
Staffing is dog-eat-dog, which works against new employees (e.g., spend more time trying to get staffed on appropriate projects than developing your skills through formal training)
Extremely subjective and distorted appraisal reviews (i.e., feedback is captured several months after the fact)
Poor project management skills (i.e., deliverables are rushed without clear timetables and prioritization is rare)
Knowledge management and knowledge transfer is dismal... you either know on your own, or you'll have a hard time finding it in a timely manner -let alone, get some solid advice from seniors... this will likely work against you at appraisal time
Arrogance like I've rarely encountered elsewhere (total turnoff and not conducive to learning... know-it-all attitude in an industry that requires inquisitive minds and questions)
