Management - bad managers, who love micromanaging and lying to your face, No support or trust. Favoritism deluxe.
Product - great product overall, however a lot of bugs and little information about how it actually works so mostly you make up something to explain it to clients.
Daily work - most boring and one dimensional sales: call, call and call more. Even if you know the client is not interested and you have nothing more to offer. If you do bad, it is your fault, never the book, lack of support etc.
Client management - we always say that we are consultants and not sales people, but accounts get reassigned so often that you can not build a trusting relationship with the client.
Work with other departments - very bureaucratic, but people in the teams are actually nice and also struggle with their own problems like CS and finance, who have not enough people to cope with all the assignments.
HR - never believes you or to scared to do anything. Manager who poison entire teams are kept in the company, which increase turnover rate.
Internal mobility - worst I ever encountered. They rather hire new people then give people a chance internally. Only company I know who does not favour internal over external candidates.
