Hello, congrats for the offer!
First, do you have any other and you are trying to compare them, or is your only option?
To your points:
1. Consulting is the background from a lot of people in top MBAs, and not only MBB, but also Strategy&. Think that they also want to have diversity in backgrounds and companies.
2. In theory, yes. Even before.
3. Best thing is to look it up at glassdoor, where actual candidates share that info.
4. If you do work with TMT, really good. If you don´t work wtih TMT that much but you are passionate about it or have a prior background, still good enaugh.
Hello!
From your message I understand that you are "trying to understand the broad areas to look at when the client is a from the public sector"
However, it totally depends on what the case is asking you for. As outlined by previous answers, public companies are many times no different than private ones in terms of what they want and the problems they are facing. Hence, don´t make the mistake of thinking they need a totally different approach.
What determines the approach is mostly the case prompt, not the type of client/industry.
Hope it helps!
Cheers,
Clara
