1 round with code test and project details. All process is onsite. Code test is from leetcode hot 100 and other basic C language questions. Generally it is quite easy and smooth

The first round is basically an assessment round in which they ask some coding & some question of aptitude. I have cleared the first round. The second round is Technical round in which they asked some question of core subject (OS,DBMS,OOPS) & some DSA question. I have cleared the second round. The Third round is Managerial Round in which they asked some question of puzzle & i am unable to solve that puzzle. I am unable to clear the third round.
