This post isn't a breach of confidentiality
But its wrong of you, OP, to post here asking for opinions - which you know will amount to judgment - on a candidate who is hoping to get a job within your organisation. But as a senior staff member you appear not to be confident enough to think this through carefully, trust your own instinct, and decide whether this candidate is suitable or not.
He put the personality test in his "brag file" - incidentally, strange you say "nice" is a requirement but candidates have to brag? Is it humble-bragging??
He'll never know, of course - but what a thought that you could go for a role, and the senior member of staff responsible for interview and recruitment, is on an internet forum asking random people who don't know you nor were involved in your interview process, whether you are suitable or not!
If you don't understand the personality test you could have gone online and found information about it. You say you've done that but if you haven't found anything in Google Scholar for instance, then I find that surprising.
YABU for not having belief in your own assessment skills yet you hold such a senior position
Talking about a candidate(even if anonymously) on an internet forum is poor form really. What would you do if the consensus was "no, don't give him the job?" trust the judgment of strangers over your own? Because if its not that then I don't see the purpose of your question really, you must want a yay or nay here to help you make up your mind
Its unfair
