The pandemic of 2020 has made job interviews even worse. There are many big companies, such as Tencent and Bytedance, whose recruitment quota has been significantly reduced, but the interview threshold has been repeatedly raised. If you don’t prepare carefully, you may be dumbfounded by the interviewer, or even lose a rare opportunity.

In 2021, the situation is still grim and the future is full of uncertainty, so those who want to change jobs for a higher salary should be prepared before the interview.
