Hi there,
Before giving my personal advice, let’s talk about your nerves quickly. And please bear with me, this is important.
If you’re like 99% of all people, you will feel them up until the moment the interview actually starts. That’s when the triune (aka reptile) brain kicks in, taking over from the neocortex. Your higher brain function is reduced to the most basic functions. At that point, you won’t feel the nervousness. You’ll just be guided by instincts and ‘muscle memory’, which is what you happen to have built over the last few months by doing lots of casing, mock interviews, etc.
You won’t realize this during the interview, but likely after. You won’t remember all the details and it will all seem a bit blurry, because you were in fight or flight mode. However, this isn’t a bad thing at all – as long as you have practiced (which you have) – and here’s how it works:
- Practice: Doing anything repeatedly migrates the part of the brain responsible for the action from the above-mentioned neocortex to the triune brain. Again, the latter is all you have available during the interview. If you have done lots of casing, it’s now manifested as part of your lower brain function.
- No practice: People who didn’t practice a lot before the interview and rely on recalling stuff rather than muscle memory from practice, will generally do significantly worse than those who practiced. That’s because you need higher brain function to recall things. Ironically, this is less true if they don’t take the interview so seriously, which reduces stress and allows them to use their higher brain function more.
You have practiced and therefore nothing to fear. My tip for the last day; don’t do any preparation at this point. That ship has sailed. You know what you know.
Now it’s time to do whatever brings out the best in your, so you can bring that best version of yourself to the interview. I’m not sure what that may be in your case, but I’m pretty sure it’s not reviewing notes or doing some final casing. It’s maybe a nice hike or whatever other activity you enjoy!
Hope this helps a bit. Best of luck!
