Current undergraduate in the US with offers for both (in large offices) and I'm currently trying to decide between the two. MBA sponsorship is a big factor for me.
Does anyone know how long you need to wait as an AC/BA at these firms before you can get sponsored for your MBA?
Are there any differences in how they sponsor you?
Does everyone at McKinsey who is passed up for BA → EM get this option as long as they aren't a slacker?
How hard is it to achieve the level that is good enough for sponsorship? Is it around top 50%, meaning an average performer could do it, or is it closer to top 10-20%?
