I post this specifically related to the LA office, my understanding is that the culture can be different in each Slalom office.
1. "Consulting" opportunities are few and far between. If you are not in a purely technical discipline, good luck getting staffed according to your skillsets, let alone desires.
2. Management on projects kowtows to clients, no backbone whatsoever when it comes to SOW conflicts, scope creep, etc. I've had management throw me under the bus first, instead of standing up to the client.
3. You will mostly be on projects by yourself, and left to yourself, management doesn't see or really ask about your work, just as long as you are staffed and paid for by the client.
4. You can't say no to a project, or you're toast. Even if the project work is completely out of your wheelhouse. You are asked to "tweak" your resume so they force-fit you into a role.
5. If the wrong person in management doesn't "like" you, you're toast. They all share subjective "feedback" with each other about you behind your back. I was told by a previous manager that your relationships are actually more important than the work you do. To some extent that is true in consulting, but at Slalom LA it is taken to an extreme level.
6. If you're not extremely extroverted you fade into the woodwork, no matter how hard you work or how good you are at what you do.
7. Lastly, the LA commutes are brutal, but management will never negotiate WFH with a client, even on Fridays. They would rather put you through a 2 hour commute each way everyday than negotiate any kind of WLB with the client for you. All in the name of "customer love". Which morphed into "customer obsession" during my time there. Face palm.
