The easiest thing is the interview. The other party has only read your resume and can't confirm whether you are in person. It is impossible to admit you by a phone call.
If you have participated in an interview outside, you will know that even if you want to recruit a general worker or waiter, you still need an interview, that is, a face-to-face meeting, to get to know you and know whether you are suitable for this job.
If you think about it carefully, you will find that there are many loopholes.
