I get a job in one company, where I need to pass an IQ test during an interview. Recommend a good test for training and assessing your capabilities. I want to try to pass it first at home, and then during the interview

Probably a very good job awaits you if you go to such tests. I can advise you to take an IQ test https://iq-global-test.com/ on this site. It is quite difficult and not everyone can pass it. If you succeed, you can be sure that you will get the job.
