Vantaggi
BT people are in general good to work with and are now the only thing which are of any merit which remains. It is a great shame as BT was a great place to work only 5 or so years ago.
Svantaggi
Huge bureacracy which is now getting stupid. Processes on processes, complexity on complexity. Senior management and HR are just worried about getting rid of people - 99% of the time that is ALL they focus on. BT has sailed very close to the wind in terms of moving people on under poor performance. The targets for this are artificial and it is very easy to find yourself in the GS (generally satisfactory) marking category - the wolves are then out to exit you at all costs. Yes, BT does have some wasters, but many of these people get away from the exit process - mainly because they run it !!!
