Ok, here go my assumptions on their recruitment procedure. I applied with them too and was invited to do the tests. Without exaggeration, I found their tests online very easy and I had done the numerical one at least 5 times ( with many similar questions from shl) for other investment banks. Like someone here in the forum, I got swiftly rejected. I strongly believe they make some candidates from other universities take the tests just to keep up their 'diverse hiring' profile. The truth is they only care about oxbridge candidates. That is why they make them sit in person. They know their shl tests online are crap and candidates can crack them easily. Shame on you Mercer people and your dirty policies. Well, anyway, I got offers from much better firms.
