Punctuality is the basic quality. If you haven't been to the interview site, you can look at it two days in advance, and don't be unable to find a place then. At the same time, you can look at the clothes of the company employees at ordinary times, and they are basically consistent during the interview. Don't cross the line. You can also talk to the company security to find out the truth. Resume should be honest and checked. Seeking truth from facts is a moral requirement and will not make you feel guilty on the spot. Don't put your unknown "big" project experience on your head, it will be very sad to be asked. Your resume should be concise and focus on your skills and work experience. The richer the better, the clearer the organization will leave a good impression on the interviewer. Dress appropriately, look dignified, talk appropriately and be polite. Among many interviewers, doing these well is already slightly better.
Design answers to sensitive questions, such as why you left your previous company. Don't say that your previous company was bad, but state it in a grateful tone. Think of some questions that may be asked in the interview, and do exercises at home to avoid being too nervous and insecure during the interview. Repeated practice can also improve the success rate of application. Be familiar with the company's business in advance, know the company's products and market situation. If you are asked to do this position, how will you start your work and report to the leader in advance, which will be clear and well-founded, greatly improving the chances of successful application! Many things happen. Don't fight unprepared battles, opportunities are always reserved for those who are prepared.
