Off-Cycle Internship, M&A

As part of the online application, I completed a psychology, math and reading comprehension test. Psychology had two statements: Pick what suits you best; sometimes both statements were very negative. Math: Mostly simple chart/table comprehension with rule of three calculations; main issue was time/speed, not difficulty as such. Reading comprehension similar: A few paragraphs with a situation and conversation clippings followed by true/false options on statements relating to the above; issue was quickness, not genuine difficulty of concepts.
