i have 8.2 cgpa in 10th, 89.6% in 12th and 8.1 gpa in btech, plus i have 2yrs gap after btech, can i get a call from BLACK

Profile is above average, you will get it without any problem. For 2 years gap, you can take an excuse like UPSC prep or anything else like disease, stage 2 cancer etc.

NO, you WON'T...!
now what would you do?
will you leave prep now?
buddy nobody can tell you what could happen or not everything boils down to your cat percentile and remember this nobody's yes or no should matter in your mind.

Goodluck!!
