Avantages
Key Difference takes care of its employees. Most of the peers are friendly and talented, so are the managers. So, I assume its a best place for me to work, same applies for you too I presume and also most of their HR policies are employee friendly. It's easy to take a day off and no one stop's you and ask questions about it.
Inconvénients
Apart from the training programs lessening in the last few days, everything else is just perfect.
