I know a thing or two about this company. They make integrated circuits, IC chips and other products, mainly focusing on research and development. The developed products will be handed over to the foundry. I wonder what position you will interview them for. This company is a domestic enterprise, small in scale, but requires high academic qualifications. Basically, they all have undergraduate degrees, and the salary is very good. If you are applying for a research and development engineer, if you have no relevant work experience before, I suggest you open 4000+. If you have relevant experience in the IC industry, you can open about 6000, which is a good environment, but you should know that this R&D-based company is under great pressure and usually requires you to develop new chips in a short time.
good luck
