Hi there,

First, congratulations! Well done on securing the dream job!

Of course, there are some ramifications to switching, but you can't not switch! This is the way business works and you've been given an opportunity you can't refuse.

In terms of how to approach the situation best, make sure you do the following:

1. Get the MBB offer in writing and signed before you do anything.
2. Give your current employer ample notice (even an extra week or 2 more than your contract requires you to)
3. Tell your boss/manager you want to finish things out properly and will do whatever it takes to make sure there's a smooth project handover

And that's it! Congrats again :)

There's no easy way to do this. The main thing you want to do here is not to burn bridges. Be polite, mention that you've always wanted this role and that the opportunity is really good to pass up. Definitely talk one on one to any mentors you have and be upfront. These things happen. 

You are moving to a higher position at a more prestigious company. One thing was moving to an equivalent position or a lower one. But you're getting something that seems to be better across the board. 

Be transparent about it. Be appreciative of the time you spent there. Ask them when would be the right time to leave. Talk about it sooner than later.

If that's your dream then no second thoughts. Go for it :).

Be nice and humble with current firm as you dont want to leave with any misunderstanding. You never know how paths cross in future.

All the best for everything!

Congrats on getting offered your dream job!

Since it is your dream job, why do you want to let it go out of your hands?

You should break-in the news professionally. Create a list of proper reasons why you want to move.

Make sure you leave on good terms - on the basis that you are going for your “dream job” and NOT that you are going for a “better job”.

As long as you are honest and transparent about it, should not be an issue. Consulting industry is a ‘come and go’ and especially second tier firms don't usually show hard feelings if someone trades up. At the end of the day, it also reflects positively on the firm and their ability to develop high-calibre talent.
