My campus interview experience 3

Last week I attended Graduate Trainee Engineer role in one company. In first round aptitude round there are 18 questions on various topics. After successfully clearing the aptitude round, I moved on to the first interview round. This was followed by a technical round where the interviewer asked questions based on the projects listed on my resume and some OOP concepts. Then final HR round is scheduled the same day but due to some power outage, I was unable to attend. That time i feel very bad about me. I emailed them, but I haven't received a reply. I hope things will change in the future.
