Pros
Not that many - above average salary, high PTO policy (that you won't get to use due to program leads and unrealistic deadlines or expectations), comradery among your peers that are in the trenches with you -- which is dependent on your program and the politicking that those around you are angling for.
Cons
Proxima has an inherent issue that has yet to be addressed - the selling point and headline is "world leading procurement and supply chain consultancy" yet nothing that is achieved or sold is world class. The supply chain practice is in its infancy and has lost key members over the past six-months, client work is sold as strategic and yet most work actually accomplished is very tactical and transactional, and leadership is not in-tune or connected to the employees and their desire for growth.
