I worked as a civil engineer on-site, having 15 years of experience, and now I am searching for a job in the city. However, I worked in a small company previously where there were no salary slips or bank statements provided. Therefore, I am looking for opportunities in a reputed construction company. They are asking for a salary slip. Can I use my job appointment letter with my salary details even though I don't have a PF account? Please suggest to me what I should do.
