PSC and efficient recruitment

The news headline “Hasina asks PSC to recruit efficient and honest people” has drawn my attention. When more than 50 percent posts in government services is allocated for various quotas, how it is possible for PSC to recruit efficient and honest people?
In addition, more than 350 government high officials including a couple of secretaries have been made OSDs for a long time. Are they not efficient and honest?
