Q23: Who approves and what qualifications must a mentor have?
The IEM will have to verify and approve your mentor. Ideally, he should have at least 3 years MIEM qualification and be from the same discipline as yours. Corporate members who have been Professional Interviewers for IEM are an ideal choice.
Q24: Can non corporate members be mentors?
Usually the person who is a mentor must be of a certain professional standing. A non corporate member of the IEM will not be able to give candidates tile right training that the Institution requires.
