I was dc in Polytechnic due to some backlogs now iam in 3rd year engineering.then this problem i will face at the time of interviews..
See if you are doing your engineering then it shouldnt be much of a problem. You may have to explain why you had backlogs. Tell them you had some problems - maybe personal or whatever the reason is. They will be interested in your engineering marks and how well you did there more than diploma. so dont worry.
