Call back is a link in the audit process, which does not mean passing the audit. Generally speaking, it takes 5- 10 days for online channel and 2 weeks for counter application, and the telephone return visit of Bank of Communications takes place during this time period. First, remember the application materials, it is best to take one with you, and keep more important matters in mind. Second, say hello to colleagues in the company in advance. The company's fixed telephone number on the application form is the most frequently visited, so you need to say hello to the person who answers the phone in advance. Especially for applicants with large companies, the bank will probably not make a phone call according to the fixed telephone number you wrote, but check the company telephone number by itself. In case the bank calls, the colleague who answers the phone just doesn't know you, and your application is basically hopeless. The fixed telephone provided is a friend's, so you should say hello to your friend in advance. Third, the mailing address of the card is particular. Try to send my credit card to the company address, which can prove that I am stable in this company. It is convenient for you to send it home by mail, but it may make the bank think that your job is not stable enough. Fourth, how to answer irrelevant questions? Now the return visit of the bank sometimes asks you some irrelevant questions to test whether your information is correct: for example, it may ask you why no one answers the phone at work. (You can say that the front desk may not be here), or does anyone in your company know you? It can be said that there may be, not familiar with. The whole idea of the whole return visit is: you must be calm and answer calmly. If you encounter something that you can't remember clearly or clearly, don't think about answering for a long time, the bank will be suspicious.
