Many people want to change jobs in the future - not me, and not most of my colleagues to the extent I can speak on their behalf. I hope my career is here and here for the long term. This is an amazing place and I feel lucky to be a part of the future we are building here.
The only negative are the administrative issues, but those are issues at any firm and certainly not unique to this firm. Billing is fairly streamlined, we have good IT people, etc., but it is still and always be somewhat frustrating to have to deal with these things when we want to focus on our work and our clients. But it has to be done, and I know of no place where it does not have to be done, so I am not sure that is a negative about this firm per se, rather, just a nature of the business.
