Vantaggi
If you have not had a professional job before, this is an excellent starting point for you will learn a lot about the real world of working and you will learn it fast. From business etiquette to basic industry knowledges, you will be exposed to it all in some degree and fashion. You somewhat have the ability to chose the path you take while at Deloitte. Meaning if you are strategic with your connections and can swoon via telecommunications, you can migrate from projects until you find your niche.
Svantaggi
There is this umbrella of unsaid but very much applied pressure at Deloitte. As I am sure it is at other large firms. The con of this is that no one acknowledges the pressure, and in actuality, they speak and act the contradiction of it. At the firm, everyone wears this face of "we are the happiest we have ever been, there is no greater place that Deloitte, I love my work/life balance" but in actuality that is not what is going on. If you are not online at all times, it is frowned upon. If you are not contributing over 100%, you are slacking.
