Hi Sathvik
Not sure what you mean here. A case with a peer or an interview?
In an interview, no.
In a case with a peer you should be getting them to send you the case they cased you in. You need to do this every single time. And you should be both tracking and reviewing your past cases periodically (the case itself, your casing template sheets, and your performance that you recorded). You should also be casing people in cases that you struggled in.
All of this optimizes your learning + prep and saves dozens of hours of extra effort.
