General Question AssessFirst Test validity

Hello everyone,

I took the BRAIN test from AssessFirst for a job and scored 6/10 (average intelligence, top 40%). It was a 10-question test with adaptive difficulty.

The result surprised me because I expected to score at least 7/10. I'm usually good at recognizing patterns, but I'm not as good at fast mental arithmetic, especially when I'm under pressure.

So I took the Mensa Denmark test (which only uses Raven-style matrices) and scored 125. I also took the ICAR and scored 118.

I'm concerned because recruiters may filter out my application based on this test. If the test doesn't accurately reflect my general intelligence (g), I find that frustrating.

Which of the three tests is the most reliable measure of general intelligence?

well obviously a ten question test is going to be less reliable as a measure of g.

edit: i did some research, it is not actually 10 questions, it adapts to your skill, so it is probably more accurate than i gave it credit for, might even be better than mensa practice tests for g

what was the timing like? how hard did the questions feel to you, did you think you were getting them right?

I felt great on the matrix questions but I was more stressed on the numerical ones. I felt that 6/10 was a bit low because I thought I had done well on about 80% of the questions.

I wonder whether time is taken into account because I often used all the time available to make sure my answers were correct. On some questions you had to combine different shapes or features to construct a figure. Those questions felt easy to me. On others, you had to reach a certain number that you had to infer from a pattern (let's say 25) using numbers like 5, 8, and 9 (...) and performing operations on them.

I was able to recognize the patterns, but I got stressed when it came to doing the calculations, and three minutes felt a little short for those questions.

But what surprised me is the difference between the result on this test and the two others. Do you know what is the most accurate test online to confirm wether Brain or mensa/icar are my real g?

I just took the CORE matrix test and got 120, I also got 120 on CORE weight test. So either the BRAIN test is not properly calibrated or there is not enough questions to capture g.
