Hi,

1. Yes definitely
2. I can talk about what I know, in Belgium, Deloitte without hesitations.
3. Really common in Belgium. Know lots of people started at Deloitte/EY and joined McK a couple of years later. However it's not systematically people who came from consulting department within Big4. I imagine that they can share their expertise in one field like audit, accouting, etc.

Hi,

1. Yes, it is, since they hire more people, the process is less structured and the criteria are less demanding
2. If you want to work for MBB later I do not recommend thinking about strategy consulting or ops consulting separately. At MBB companies you are doing all types of projects. In Big4 it is a bit more specialized, however, the strength of the team really depends on the particular country and the partners of the particular team. (e.g. E&Y metals & mining team may be the best ops team in a particular country because of the strong partners and will be completely underdeveloped in another)
3. It is quite common, and now it is happening both on the early levels and senior levels. So answering your question - this experience is very relevant

This to answer the question in the "comments" section on what I think drives to have more transitions to MBB from TAS vs. other practices of Big 4.

In my opinion is all about the knowledge of PL and BS, the understanding of value implications of cash and non-cash changes and the practical approach in understanding what things need to get done to close a transaction.
