I have participated in an interview in Zhongguang, and the written test feels like some brain teasers and some basic operations. For example, it takes XX days for a planet to orbit a star, and its rotation speed is XXM/s. If the radius increases XKM and the rotation speed remains the same, how many days does it take to orbit?

Two people take 16, and each time they can take 1, 2 or 4. Whoever gets the last piece loses, which one do you choose first or later?

How to connect nine points arranged in a square with four straight lines and so on.

About a dozen. I can't remember.

Then, when you do the questions, some people will go in for an interview, and almost all of them will roll up after the interview.

When I went in for an interview, three people went in together. We are in the same school.
