Where do you work that psychometric tests are required of candidates? It's the first I've heard of something like this (outside of various gov't/military jobs).
My current company do this, we've around 600 employees across Europe and every candidate for an IT position in the UK takes the same test at a 1st/2nd level interview.
Unlike the OP it's at the hirer's discretion how much weight they put in the score and it's made clear to us there's a definite pattern that more nervous candidates & those without English as a natural language score less well. We ask them to come into the office, only in rare occasions does someone do it remotely.
Most of my candidates in software positions score 40-70% and have done well in the company, I've had a number in the 0-20% bracket of whom I took 1 based on his good performance in other aspects of the interview - he's not turned out to be a great hire relative to the others. A handful in the company get the 95%+ scores and they've all done well - I think many are among the best performers in our department suggesting some kind of particular capability.
The output of the test is a % score with breakdown in a few catagories plus a 2-3 page personality profile. I showed mine to a few ex colleagues, it said probably 8 things like "will have days where he's uncommunicative or seems unfriendly and days he's warmer" which everyone pointed out as eerily true about me (and the negative aspects I can therefore work on!) but it read a little like a horoscope in that you can probably find truth in it and it's up to you to what extent you forgive the paragraphs that are very untrue, although presented in a scientific way.
Honestly, I think it's pretty helpful as accompanying information and would use it again at another job
What would be awesome would be taking a variety of (cheap, painless, ideally totally passive) tests on a control population, your applicant population, your offer population (specifically those who turn you down), your new hires, and your ongoing employees (especially if you can sort your employees once hired into good/bad).
It would ideally be descriptive vs. prescriptive, so you could uncover things like "we get mainly recent-college-grads applying, but our strongest employees are those who joined mid-career", or "we have very few minorities who apply, but those who apply and are offered positions tend to be strong and stay with the company a long time".
Pretty meaningless unless you are hiring at Google scale, though.
In the UK a lot of otherwise sensible organisations seem to include these daft wee tests into their hiring process (including at least one large US tech giant and one fairly successful VC funded startup that I know of).
It's common with big companies in South Africa as well. It may have to do with how difficult it is to fire someone under our laws, but a few months probation is usually good enough, and fairer.
Software consulting places and body shops (unfortunately the line is increasingly blurry) don't generally do them. There was small software company in Jhb that used to send candidates for invasive IQ and personality tests to a psychologist, but they don't exist anymore.
Many big corporates have psychometricians on staff. At least one even has a department dedicated to psychometric testing.
There's plenty of demand for skilled developers so I don't understand why people put themselves through the humiliation. I expect that a lot of skilled people self-select out of these sorts of psychometric processes if they can, to the detriment of potential employers.
I also wouldn't be surprised if many of the tests contain an element of uncorrected racial/cultural bias, and the psychometric industry has been exploiting the inability of the government to enforce the law (Employment Equity Act), which makes discriminatory testing illegal.
"I also wouldn't be surprised if many of the tests contain an element of uncorrected racial/cultural bias, and the psychometric industry has been exploiting the inability of the government to enforce the law (Employment Equity Act), which makes discriminatory testing illegal."
Bingo! The way it actually works is you organize everything with the assumption that applicants will fail 20% of tests. A different failure mode each time, but the odds are excellent if you give an applicant ten tests, and they fail 1 in 5, every applicant will fail at least one. Then you remove all the undesirables (skin color, sexuality, that kind of thing) and declare the fact that the bosses nephew being the only guy to fail the 360 interview with the janitor turns out to be not relevant, so lets hire him.
In the original article the only reason the 1% test result mattered In That Particular Case is the HR person didn't like that asian's nationality, or race, or religion, or something like that. Guarantee if I was the candidate it would be swept under the rug (unless the HR lady hates me because of my race, politics, religion, of course)
"I also wouldn't be surprised if many of the tests contain an element of uncorrected racial/cultural bias, and the psychometric industry has been exploiting the inability of the government to enforce the law (Employment Equity Act), which makes discriminatory testing illegal."
Why would the psychometric industry want to exploit such a lack of enforcement by vending a discriminatory test? Do you think their customers are interested in using tests that give bogus results?
Perhaps I was unclear. I don't think that they deliberately bias the tests, I do think that they don't rigorously validate the tests to prove that they are non-discriminatory, perhaps because of laziness, or because they lack the statistical know-how.
Section 8 of the Employment Equity Act:
“Psychological testing and other similar assessments of an employee are
prohibited unless the test or assessment being used—
a) has been scientifically shown to be valid and reliable;
b) can be applied fairly to all employees; and
c) is not biased against any employee or group."
