L1, L2 Visa

I have reached before 11'o clock since my interview time is 12.00p.m.Inside a pre-screening of my forms upto BEP letter they have taken. And the lady who sits in the counter told me to wait until they called my name to return those forms. So i waited upto 12.30 inside. Then i checked with a person who is giving instructions to us . He also has told the same. After some time our names called. They got these forms from other building. ( I think they have taken these forms in other building after some time they have returned back). Then went inside in second building without standing in Q. After finger print scanning we have stood in one Q which is near to finger print scanning counter. After some time one instructor asked us to stand in counter 8. The interviewer in counter 8 is looking serious. For none of the candidates he approved. (since when i sit there i observed this counter).
    When my turn came i went along with my husband. I wished him Hello. He asked docs and marriage certificate. I have given. After he asked 'How long are you associated with xxx?' I answered I have associated with xxx from past xx months like that' Then he asked my husband to sit in chair so that he wants to talk with me. He is looking in computer and saw the passport and docs. He asked about technology. I said Mainframe technology which has cobol,jcl,vsam,db2,idms. Next he said speicalized knowledge should be only for business executives etc., ( I did not hear properly) but i understood he is not accepting. So i am telling like i have specialized knowledge on idms. but without listening my words.he has taken blue slip which he has bunch of blue slips with him and told show to your HR by selecting option "your blanket L-1 application is not clearly approavable under section 8 CFR 214.2(I)(II)(D) and INA 101(a)(15)(L)". I didn't get what it is.
