At grad level, there's not a lot of difference. Mostly analytical work and calibre of colleagues generally the same.As you get older, consultancy loses its allure. You see the IB boys suddenly buying Porsches and penthouse apartments in Docklands. As they get older, they start buying Bentleys and 6 bed houses in Hertfordshire. You, on the other hand, as a consultant, are still chipping away at the mortgage on your 2 bed flat in Woolwich. In order to get the extra space you need as your family expands, you move further out of London and maybe get a reasonably OK 3 or 4 bed house in somewhere like Orpington, Kent. You find yourself suddenly working with "experienced hires" who have no prior consultancy experience, and probably not much in the way of brains either. Middle-aged women who fancy "getting into consultancy" before they get bored of it after 2 or 3 years and go back to working in the public sector or something. Older men who dabble in it to supplement their retirement income. Other folk who have soft skills only and who can run a brilliant workshop where everybody is nicely entertained, but where the project itself turns into a crisis because they can't write a report or deliver against the brief. To console yourself, you consider that you are lucky to be working only 50 hours a week (plus commute time) in contrast to your IB buddies who still haven't left the office since they were 21. Except, deep down, you know that's not true. The IB guys do work long hours, but perhaps not quite as long as you had thought. They do get home by 8 or 9pm every day. You yourself often end up working those kinds of hours too. Except they now earn about 10 times as much as you do.So basically it's down to barriers to entry. Anybody can call themselves a consultant, which makes life hard for the good guys. Not everybody can call themselves a banker though - and that's why they earn more. Alternatively, get some proper skills and become a surgeon or something. Even better, become a GP and earn £130K/year just for dishing out paracetamol to old grannies that complain of back ache whilst working 9-5 from your cosy country-based practice.
