A lot of other people who took the test got largely the same result as when they joined the company — my results had worsened (by the HR Manager’s standards) — she later told me that I was anti-authoritarian and more likely to do what I thought was right rather than what I had been instructed to do. […]

She mentioned that my chances of securing the job upon re-interviewing at the company were slim due to my psychometric profile.

What a nice thing to say to one of your senior employees. HR people really are something else. They could’ve easily lost him that day because of some random bullshit.

Anyone who codenses candidates down to a “score” or a "number is doing it wrong.
