I totally agree. Go for the big firms if can. B&F is a very good field because we are a major financial centre. All the international firms set up shop here to do B&F work. While M&A is also a good field, but it is more niche and there are times when there are few deals. Besides your M&A TC is with a mid-sized firm, so you may not be involved in the biggest deals in the land or region. Go big firm B&F.
