Why can't the newly recruited staff of public institutions sign up for the examinations of other public institutions during the probation period?

Because you may become a full member during the probation period, you can't take the exams of other institutions. Otherwise, your job-hopping will lead to the waste of personnel indicators of the original pilot unit. At the same time, it also shows that you are picky about your existing job, and your work style is not practical. Thank you for your adoption. Give points.
