I'm in my final year of university and applied to a role which is an exact match with my internship experience this past summer, which is a somewhat niche industry. The company I interned with is a (less successful) competitor of the start-up I am interviewing with. So far, I've done a recruiter screen, behavioral with the hiring manager, submitted a case study, and now have an interview with a senior vp about my case study with some behavioral mixed in. This is my first time making it this far in the process and first time with a take home assignment.

What are your best tips to prepare? I won't be presenting my deck bc the interviewer will have reviewed it and ask me questions. Any and all advice is appreciated. I have been using STAR method, giving concrete examples, and researching the company/culture. Beyond that, what can I do? What kind of questions are asked during the case study interview and second round of behavioral?
