Didn't BYD send a text message?

First of all, don't worry! Compared with my career, the rest of my life there is very long, and half a month is not too long.

You can ask again and see if there is any result. You can also ask the person who applied with you to see if there is any news.

In addition, you should be prepared not to be hired ... make good use of it and look for other opportunities ... the more roads, the better.
