Vantaggi
Some projects have great visibility and give you the opportunity to travel internationally at a young age. If you get tapped internally you can spend time on cool projects and learn a lot. There are very cool sides of Accenture that are worth joining -- Accenture Digital, Fjord, Accenture Interactive.
Svantaggi
Long time's spent on the "bench", waiting to get called on projects. You would wait 3/4 months waiting for a project, but interviewing for new projects. Management gives no clear guidelines for skills you should be picking up to make it easier to get slotted for projects. In my starting vlass, most analysts were given projects where they mostly sat all day and did nothing. Projects and Roles are found via interview process. You need to interview internally at shipper for roles, creating a lord of the flies type situation. Where everyone is competing, and networking all the time to get the best roles. But when you find a good role and are accepted for the role, you would often times be pulled from the project last minute because an MD had a 'pet-analyst' they were looking out for and would staff them instead. The guidance was very unclear and unstructured. Projects are sold to internal employees as HL strategy projects, but are mostly copy-paste implementation solutions for SAP, Oracle, Salesforce, etc. Moreover, it's downright impossible to get off of projects, you could be stuck for 6-12 months in a clerical role. If you're looking to build skills in consulting, it's only "good" by name itself, but overall think I would have preferred to go to a startup, or different firm.
