Senior leadership could be very difficult to work with
A major project that was extremely resource- and time-intensive was ultimately a failure because leadership did not listen to our suggestions that the product was far from ready (bug-ridden, overpriced, questionable value for consumer, tons of errors, poor UI, etc) and it eventually became a bit of a boondoggle for the company both due to botched launch and exceptionally poor CS
Overall, customer service was very poor
Extremely high turnover rate
