CA Mayank, Please show some level of maturity. You should not try such act, it only reflect the hatred which is not a moral act. Further if you say that he has cheated his company imagine if your friend’s real fact is revealed, one day or the other to the company.....he himself will realised what he has done. This could have impact on his career ahead with the company.
On the other hand HR find reason to reject an applicant, so they are very smart at that....So be positive and leave it to the "Niyati to Decide". Further look for better opportunities mean while, and update yourself with more in your CA final subjects....even though you have cleared....!
