Question: I have graduated in Electronic Eng. Is it possible to
switch field to, let's say, Petroleum related. I am willing to study
further related to that.
Answer: It’s always possible to change fields. You should not feel bogged down by a career the you’re unhappy with. In Engineering it will require an advanced degree in the new field (such as Petroleum Engineering). Before you make this change take some time and really think about your career. You do not want to invest the money and time in acquiring an advanced degree and then find out that you don’t like that field. Another thing to remember is that you may also be required to take an entry level position in your new field which may impact your salary requirements. Good Luck.
