why are you still punishing yourself after the incident?

If you feel sad, that shows the act of you yourself is punishing yourself for someone else's fault. This is very unhealthy kind of feeling. Don't rush to forgiveness. In this incident, it also shows that who are your friends and who are not. If you are so clear they ain't your friends anymore, what are you bothering then?

Please be more organised, you already screw up the interview just now because you bothered too much on what to do and what not to. They don't even care, they don't even think of it. Just distance yourself and be careful next time.

To be able to stand up in an interview, you have to read more!! And talk about something you are passionate on. Read newspaper everyday and of course take care of your thesis too!Thesis and General Knowledge!! Others are just sidelines.

Always remember how disappointed your supervisor looked like when you are so lack of your general knowledge. I think I just shamed my supervisor in front of other lecturers Oh mann! Because they're bias towards engineering students, and asked me to give my professional advices! How would I know because I'm not really passionate on it LOL Talking on something u're passionate on is a plus point! like flute! :D
