Additionally, make sure to do thorough research – research the role as well as the company and its values. Research the industry well, especially how insurance providers operate and the ‘hot topics’. Also know the specifics of the company you are applying to, so you can tailor your application.
Come with an open mind, be yourself and be ready to experience new challenges.
