The Final Six (The runaway Japanese bestseller) - Akinari Asakura

Shogo Hatano has beaten thousands of applicants to become one of six final candidates in the running for a graduate position at Japan's most exclusive tech company. But Spiralinks will only make an offer to one of them, decided by a group vote in their last interview ... As deliberations begin at the glossy high-rise office in Tokyo, Hatano finds six envelopes addressed to them all. Each contains a shocking revelation about one candidate: six secrets so terrible that they could ruin more than just careers. They could destroy lives. With the clock ticking, Hatano must figure out who planted the damning evidence and convince the others that he deserves the job of all their dreams. But one person in the room is a monster capable of anything in the pursuit of their goal. Or is it possible that, behind their polite masks and slick words, six monsters hide in plain sight? Are any of them truly who they say they are?
