I work for PA, having moved up to PC from C about 2 years agoAs with much else, it depends on the client, but most client days are 10 - 12 hours, on top of which you are expected to contribute to thought leadership (TL), sales proposals, etc. Overall the hours end up being very long from Monday to Friday, but you can usually manage to keep Sat and Sunday free.I've had to work most of this weekend, but that's not very common (maybe one weekend a month or so)
