Does Lydia need to wait for a week's notice after the interview?

No, they are very deceptive. I waited for a week and called every day to say I didn't know. As a result, on the last day, I called the personnel department, and the personnel department said: the notice of recruitment has been sent out. I'm out. Fortunately, we are prepared, and other companies will not delay, otherwise BYD will really drag us to death!
