Any Advice for Business School Interviews?

I'm currently a senior at a top 20 university, majoring in [Your Major], and I'm about to start my career in marketing after graduation. My long-term goal is to apply to business school after gaining 2-3 years of work experience. However, I'm feeling a bit uncertain about what to expect in the interview process, both for business school admissions and for internships, particularly in consulting or investment banking, which might be a pivot from my marketing background.

I’m especially curious about the following:

Business School Interviews: What are these interviews typically like? What key qualities and experiences do admissions committees prioritize? How do I best present my background in marketing to align with what top business schools are looking for, even if my experience might seem less traditional?

Consulting and Investment Banking Internship Interviews: If I decide to explore these fields, how much emphasis is placed on prior experience? Given that my background is in marketing, how can I best position myself during these interviews? What specific skills or stories should I highlight to make a strong case for myself?

Preparation Tips: Are there any particular resources, mock interview strategies, or personal experiences that you would recommend as I prepare for these interviews? I’m keen to learn how to effectively navigate these processes, especially when my experience might not align perfectly with those who have already worked in these fields historically.

I would greatly appreciate any insights or advice you can share. Thanks so much for your help
