Hello there, Im a Mechanical Engineer. I passed out in 2010 and have worked for 6 months in the Middle East as a Trainee Engineer. Im now in India and due to appear for an Interview for a firm in the Middle East. The post is of an Automobile Engineer. Im kinda nervous as to what to prepare for the interview. The training which I got was in different areas ranging from technical to managerial aspects. What I mean to say is that that was more of a crash training, where I couldn't stick to one section alone. The interview which Im attending is more of a technical one. What I would like to know, how and what I should be preparing? I have two weeks for the preparation. Should I go through the normal automobile aspects or everything in random. PS: I have excellent communication skills, the one area in which I'm very confident.
