2 Hour Case Study?

I have a 1 hour interview followed by a 2 hour case study coming up, both of which will be onsite at this firm’s office in a week.

I have already had a 1st round phone interview with an Associate and a VP which went well.

The problem is I have NO on-the-job modeling or modeling test experience. I have about 3 year’s experience in a CRE finance biz dev/sourcing role.

I have fully completed the A.CRE and BIWS courses, and built some simple models on my own time, but I have zero gauge on where my skill stands compared to these cases given. The BIWS courses are labeled as “case studies” but there is no way in hell I would be able to make models that detailed from scratch in just 2 hours.

The firm works on development, value-add, and core deals, all property types. I guess I should expect the case study to be any one of the scenarios and property types?

I wanted to see if everyone could share brief summaries of what their prior 2hr+ case study interviews looked like, how to practice, just to get an idea of what to expect. Of course, tips on how to best prepare myself would be welcome. I mentioned in my initial interview I don’t really have experience with Argus, and my interviewers didn’t seem to mind, so I really hope they don’t ask me to use it or I’m screwed lol. Would asking the HR rep about case study details cause a red flag?

I really want to knock this out of the park, I liked the guys I spoke with and the firm seems like a great spot to start.

I appreciate any feedback/advice, thank you.
