Hello everyone! I would like to ask who worked in Wuhan Baijuncheng Technology Co., Ltd.? Is this company reliable?

I have seen that company before. It seems to be in Optics Valley Software Park. I checked this company before, and I have a little impression. I didn't dare to go, and I felt irregular. Now I am working in a regular unit, and the provident fund inside is paid from the signing of a formal contract. The probation period is generally 1 to 3 months, and generally small companies do not pay the provident fund.
