We are sincere in recruiting. We do not require applicants to meet every condition. As long as you can demonstrate or convince us in the interview that you have the ability to learn quickly and have the potential to grow in technology. I don't know if this is considered a benefit, but at least the company does not advocate overtime. In Shenzhen, where companies generally work overtime on Saturdays or have a long and short week, we have two days off a week.
