It is later revealed MC should have led - in the resume sent to Reina who actually read it, even her business partner actually read it to find it fluffed, and in the interview and in his talk with possible employers before the interview - with the fact he had a working robot dog with the accompanying A.I. as his project for finishing his education. Instead, MC erased all traces of his past, including anything he is actually good at, just because everything seems to remind him of vulvamort. MC fluffed his resume leaving all his actual acheivements out, including his former job and his former employers, leaving him exposed when vulvamort told Rei he lied that he had never been employed with her company, seeing as they were business partners and all. MC chose putting in the totally useles valedictorian achievement and still wondered why he was never getting any job. That is something that is good for talking Rei about in private but useless in any interview. MC gets / looses the job on other criteria than him researching the company, that is just one tick in a long list of checkboxes.
