I have the eligibility and had applied online to OGDCL but my name does not appear in the NTS list of candidates.

Did I miss something, like applying separately to NTS for the OGDCL test.
Though I did not get any email notification about any further applying like applying to NTS separately after I applied online on the OGDCL website.

Any help will be much appreciated.
