Good on you for de-risking the situation beforehand! There's two scenarios I can think of:
Scanrio 1: Interview starts when you get the info
In this scenario, I would not necessarily expect anything different from the cases you've encountered during your practice. Most cases have exhibits, such as tables and graphs, and are usually presented in a certain sequence. This is especially the case for interviewer-led cases at McKinsey. However, other firms or certain interviewers provide information up front. This happened to me at BCG and even at McKinsey, and to many other people at various firms. Most likely, the material includes the usual i.e. graphs, tables, illustrations of a process, etc.
Scenario 2: You get time with material before interview starts
In this scenario, the interview will likely be very different from what you're used to. Candidates are presented with a bunch of information and are left to themselves for a certain amount of time. The candidate goes through all the material and organizes the information and the interview starts when the interviewer walks in 30-60 min later, let's say.
If all you knew was the duration of the total interview, we might be able to tell you if it's scenario 1 or 2.
Hope this is helpful! Let's wait for other experts to chip in, especially those familiar with Inverto (full disclosure, I am not).
