Recruiter: generic questions (why Express Scripts, why do you want to leave your current company, what is your greatest strength, etc)
Hiring manager: situational questions (tell me about work you did that wasn't your best effort, tell me about a time you gave an innovative solution to a problem, tell me when you questioned the efficiency of a process and what was the outcome, etc)
Director/VP: cultural fit (they really give you more detail about the job, questions like are you comfortable communicating to people at different levels in the org, seeing if building relationships in the workplace are important to you, etc)
