If it’s open posting, they cannot block you. If the other school accepts you and you click accept on hrms, it’s a done deal. Usually, P wouldn’t block or say negative things one. Do you really think they are so childish? Unless you have made serious mistakes. Otherwise, they will be very factual. Do you know it also looks bad on the P if their staff is not good? It shows that the P hasn’t done anything to help the staff improve.
