So I'm the president of my unis rocket club. The thing is, petroleum jobs got money and although I would apply for aeronautical companies first, just as a backup. I wanna apply for the petroleum companies. Do you guys think that this can work out? If it can't work out, may I know why? And if maybe, what I should do then?
To repeat my previous answer, but in blunter terms since you ask the same question again:
Interviewers don't have any interest in what fancy titles you give yourself.
The interesting thing is what you, and the club you claim to be president of, actually did.
Nobody expects a would-be petroleum engineer to have spent his/her spare time digging for oil. What counts is doing something that is practical engineering, or managing a practical engineering project.
