What is the written test of Huali Microelectronics?

Born out of a psychological test in Japan, the specific name is unknown.

The content is:

N rows of numbers need you to add within 10. As long as there is no obvious random calculation, it doesn't matter if a few figures are slightly wrong. In fact, this requires you to do continuous high-load thinking. Then you will be asked to change the line every once in a while. Look at your position every time you change lines, and you can determine your concentration in a specific period of time.

Just to remind you, this test is not as much as possible in each line, nor as general as possible, but depends on your high efficiency-low trough-adaptation (rebound) curve. The result of normal people will be such a trend curve, but only HR knows how high and how low it is. I finally get a concrete curve result, which may brush you off.

Just do what you can honestly.
