Pros
Being a part of Deloitte means you get projects with good budgets, and that's always nice. There's time to work through ideas and do them well.
Cons
They teach clients about empathy but there is no place that lacks more empathy than Doblin London. The management are so busy so they have no time (or interest) to support and build teams and great culture. They have their own agenda to become partner or director. Everyone else can just sort out their own lives. It's impossible to actually innovate at Doblin since they have a firm way of working. That's the only way but funny enough, they won't tell you what that way is. You just have to figure it out through trial and error which is a huge waste of time. The lack of trust and support means that many team members are heavily under-utilised whilst the trusted people are overworked. There is no culture and and nobody cares about anyone but themselves. I wouldn't even recommend this to my worst enemy.
