During your exit from a company most ask you to go through an interview exit as a formally required ,most employees tend to go off and speak their minds ,that can be very tricky in as much as you may seem displeased try as much as possible to be very professional and look at the brighter side be optimistic as you can because just as you evaluate them ,your future employers may want to seek valuation from them before employing you.

If you understand the double edge sword principle you may want to avoid such occuarnces because ,in the cooperate world is even more brutal than you expect .Try as much as possible to stay calm as much as you can ensuring you are capable enough.

Make your moves in silent,is very dangerous if you want to be frontal with your former employers and be professional as much as you can.

The good news is you are leaving anyway so be wise and dont be quick to burn the bridges you cross.
