You absolutely need to be prepared for both a case and a fit interview.
For fit, be prepared with answers to "resume walkthrough", "why consulting", and "why EY" as well as have 5-7 personal stories prepared.
For casing, you need to feel comfortable with both generalist cases and PE/M&A cases.
I highly recommend you get a coach ASAP given your lack of preparation and short timelines.
