I was recruited out of college, so the process may vary depending on the stage of your career. The hiring process consisted of an off-site interview, as well as an on-site visit. The interview was behavior based, and standard "STAR" format was the preference for responses. My recommendation is to be prepared to answer the "basic" interview questions regarding strengths, weaknesses, challenging experiences, and demonstration of initiative; having an awareness of these types of scenarios will help you answer any behavioral based question. Additionally, be prepared with questions for the employer, and show initiative and interest; this can help you in demonstrating ability to critically think about the role, opportunities long and short term, and general personal style.
