Choose a few interested people to have a look, bring your resume and have a brief understanding of their company and the position you are applying for. In addition, it is suggested that in order not to waste time, it is best to call you for an interview and ask questions you care about on the phone, such as company address, working hours and work content. You don't have to go if you don't think it's appropriate. If you think everything is all right, go for an interview. I hope I can help you!
