Yes brother they should be appreciated, but filing in court is the right of others who are rejected despite of getting good scores in NTS. They appeared before the same panel if their gut feeling is saying something is wrong they have every right to inquire about it, the only option they have is filing a case in court.
And those who say that filing case won't help just check the job application statuses on OGDCL website which were supposed to be filled but they are not.
Those who are selected should not worry, and believe me most it wasn't my first interview :P
