Yesterday, I submitted my resume in Worry-Free Future. Chengdu Yicheng Technology Company asked me to go for an interview. What about this company?

If this company is your own resume, then check the company's business scope and other related information online. During the interview, the examiner may ask you if you know anything about this company, and then there are some basic interview skills. Be generous when you go and introduce yourself, especially about your work experience. If you didn't send this company by yourself, you should think twice, especially if you can't find it online, which is not very reliable. The above is for reference only.
