I would refer my friends to prepfully because the session helps candidates organize their thoughts with proper structure and helps the candidate understand the nuances specific to the company they are interviewing with. @coach - Thank you for your prep session yesterday. It was extremely useful and helped me rethink my approach to many case studies. Your feedback helped me understand how I can structure my answers better.

Learned more about how to properly go through a case study in one mock interview session than I have in weeks of using books and online materials to prep. Provided super thorough feedback on areas where I can improve and I left feeling much more prepared for my future interviews.

Thank you for all the feedback, *******!  I plan to work on it and show up more confidently for my actual interviews. I found your thought process on approaching metrics helpful and want to adapt that as well.  This is a good way to simulate actual interview experience AND get feedback l. Most of the times you don’t get feedback after interviews. This is a good way to work on your weak areas.
