Be an expert. â€œDonâ€™t say â€˜I donâ€™t know,â€™â€ says Pope. â€œThat is the death stroke. They donâ€™t want to hear that. â€˜I donâ€™t knowâ€™ will get you dismissed real quick.â€ Give the impression that you are abreast of everything. If they ask you a question and you donâ€™t know the answer tell them that is something you are exploring.
