thanks for the clarification; as for the points above, the internal strategy division can be considered equivalent to the in-house consulting (of course, with a very specific focus).
You have not mentioned that explicitly but it sounds that you are considering/have offers for Internal Strategy and a Tier 2/3 consulting company. Unless the Tier 2 is Oliver Wyman or ZS Associates, which have strong positions in Financial Services and Pharma respectively, it sounds Internal Strategy would fit better your goals. After MBB indeed you have mentioned you would like to move to internal strategy division of a bank/pharma company anyway, therefore moving there before sounds a more natural option. Unless you go for OW/ZS, in a Tier 2/3 you may end analysing industries unrelated to Pharma or Financials Service, thus marking your goal more difficult to reach.
Compared to the ideal path of MBB+Internal Strategy, you will likely move a bit slower as for a career path (with MBB before, you could likely skip a couple of years of junior position), but you would also have the advantage of understanding better the environment.
Feel free to let me know in case you would need more information.
