PS unfortunately you've been slightly miss-lead if you think you're getting on a management consulting grad scheme. You will be on a grad a scheme which has excellent training but it's quite wide ranging in terms of the type of roles you'll be doing. If after the end of the 2yr prog you're still interested in consultancy you'll need to apply to join Global Consulting which is another full-on recruitment process including assessment centres , presentations etc. even though you've been in the company 2yrs.
Investment in grads is unparalleled at BT. You get 3 two week training sessions over the course and a self managed learning programme running for 14 months in the middle. It’s flexible and allows you to make decisions to shape your own development.
You need to think about what you actually want to do. Will BT help you achieve this or would you better off at another firm. If you've already decided MC is for you then I think you'll probably get better assignments at the likes of ACN & DC. If you think about what BT does everything is associated with their network so unless it's driving traffic down it or associated with it in some way, they won't go there. No more systems integration projects like the NHS LSP. It’s difficult to be a management consultant when you don’t own any client relationship and you have to go through account teams who stick to the familiar products and networks.
The BT person posted above is on a different scheme to what you’ve been offered. He’s still “hard wired” to a line manager whereas you’ll be a flexible resource (i.e. people manager and task manager). Essentially this will give you more flexibility to escape from tedious projects. This is just some of the mess that exist after integrating a small agile consultancy firm (Syntegra) into the BT juggernaut.
To summarise… if you’re keen on management consultancy go elsewhere. If you’re not sure, you can give BT a go. You’ll get good training but some potentially mind-numbing projects (many of which are internal).
