I can't get into nitty-gritty detail like I want because they have you sign a NDA, but I'll tell you how I prepped for my CRNA schools interviews (including TexWes) last cycle. I was accepted.
-Know the type of patients you get (9/10 any committee will ask you this Q). Don't bring up any patient you are not willing to expand on. I love sepsis so I had studied the pathophys, treatments, pressors (all the way down to the cellular level--know this for your commonly used pressors, sedation, etc.), hemodynamics, labs...
-I watched all of the Ninja Nerd cardio/pulm Youtube videos and I am VERY glad I did. It helped a lot. I also watched pharm Youtube videos and bought a used pharm book to really get a better understanding of the drugs.
-After hearing about other people's experience at CRNA program interviews, I expected them to pressure/intimidate me. I told myself it is like a game, don't fall for the tricks 😉 . Helps make it less scary LOL Take a deep breath, don't rush yourself, be honest if you don't know the answer. I was grilled, but fairly prepared. When I didn't know something, I was honest and expressed that I would love to learn more about it. They do not expect you to know everything.
-Trust your gut. Breathe. Remember they are trying to gauge how you critically think and carry yourself. Remember you are trying to see if they are a good fit for you too!!
P.S. I recommend asking TCU what would have made the different for an acceptance for some constructive criticism. 🙂 This is common to do. Learn what you can from that experience, and then move on! This is a new opportunity and it will be very different from TCU. Don't bring the baggage ❤️ Both schools liked what they saw on paper. You just have to seal the deal!!
