I had a bad experience with unprofessional manager who was impatient and had over committed to the client and used to take it out often on the team. When i escalated it to the upper management. Initially i was reassured as his behavior had been a known problem within organization. But as the weeks passed the upper management started to say - "Even if he is doing it, he is still your manager"
This was absurd and we mutually agreed to end the relationship in a cordial manner. But this experience was not aligned to deloitte values aligned to developing and nurturing talent.
The manager was really insecure, impatient and when he learnt that i had escalated. He started to act vindictive. Overall a very suffocating expereience.
For a organization that prides on flat hierarchy, my experience is a telling tale of a highly bureaucratic/politics organization.
Summary - Pick your team and manager. There are a lot of unprofessional people in deloitte who have the glib and aura of superficial/theoretical client service.
