Hello,
If your question is having backlogs effects your placements, it is subject to the way you participate in the interview and your mtech performance. If you answer the questions during the interview like a pro, then fret not. You will definitely get good job. If you don't have a clarity about the subject and expecting a job in the world's topmost companies, then it is not fair to assume you are going to get a job there. If you are having backlogs then you should definitely be great during the interview.
Good Luck!
