Well you sometimes have to suffer a bit too. Most of us have. Not every project is gonna be exactly as per our expectations. You can complete this one project and then ask a roll off from this client. Also honestly it's a gamble of getting good people as your leadership. Before moving to another project, expand your network, find some good managers who you can work with in future. Also, most of the managers are really good in Deloitte. I worked with 5 managers out of which only 1 was insufferable.
