@MuhammadAhmerSheikh, Probation period is for one year and it is a normal procedure in every government department either BPS or SPS, now I don't think so that SUPARCO collects a security report from SHO which is usually a useless report. In your pay package detail there would be a amount mentioned as "Total amount without subsidy" and I think so that would be your starting salary.
