Is there a written test after Huichuan technical recruitment interview?

A written test is required after the interview of Huichuan technical recruitment. There are three aspects of technical recruitment in Huichuan: a simple written test after the presentation, and a professional written test after the interview the next day. The written test after the presentation is generally difficult, a simple electrical problem. The second written test is a professional written test with strong professionalism. Personally, it is not difficult to think that it is basic knowledge. Education is more important in the interview, giving priority to 985/2 1 1.
