Document submission calls,Security Clearance Phase
 

hello
hope everyone is fine.
most of the selected candidates for Assistant director post already experienced the security clearance calls and visits. But now few candidates received the hec attested documents submission calls but mostly candidates who experienced the security clearance didnt received any calls for document submission.
Any idea
1:why only few candidates were asked for document submission?
2: the remaining candidates can expect these type of calls in future or not?
3: documents were never asked in past year vacancies why this time?

Which post did you apply for? General, engineering or computer programming?
