First interview is a phone screen with HR, incredibly easy. HR will just ask if you are capable of commuting to Sloan, if you’re okay with the pay range hours and dates. The hiring manager has likely already seen your resume and whittled their list down to <10.
Second interview will be with the hiring manager and very casual and free-flowing. General questions about school experience, interest in the role & Sloan in general, and skills/abilities.
