I don't know your situation. I once worked part-time in Dalian Decathlon for one year. On the surface, English is very strong, but in fact it is rarely used. If you want to interview for the position of manager, you need to use more English, because they often have meetings in English. If you are interviewing for a full-time position, just remember a few simple words! After all, don't forget that people who go to Decathlon still have to communicate with people in China. I hope I can help you! good luck ...
