i think for all the big 4, there'll be peak and off-peak periods. there'll be times when u work til early morning for weeks/months and times when u can take leave for a few weeks/months in a row. either way big 4 is the way to go in terms of exposure to bigger clients. better job prospects in the future as well. as an auditor PWC / EY would be the best places to go based on the clients they have.
