Pros
It might sound cliche but the Pro for me is the people that I work with. I'm lucky enough to be staffed in a team with great leadership. Managers are actually willing to coach junior members and be a real mentor. I very much appreciate their efforts.
Kontras
Long hours and office politics. This is pretty basic and obvious for any public accounting firms. Every time a quarter end, year end, or a special filing is going out, you can expect 10-14 hour days. It might be fine in your early career but it gets really tiring after a few years.
