Vantaggi
As an intern at PIRA I was both surprised and delighted by the consistent effort on the part of my colleagues to make me feel like I was one of the group. If you have any interest in moving into energy consulting and want to get an inside look into this field and be surrounded by great, intelligent people while you're doing it, PIRA is 100% the place for you.
Svantaggi
Can't think of anything, really. Those not interested in energy markets, or don't like research-intensive work might not be cut out for it. Also, the environment might be a bit different with the recent Platts merge, so be aware of that going in.
