Hi Chris,
First off, I agree with everything Vlad has mentioned above. I recently had a similar situation with my final round interviews too. Having a big break can seem tough but use this opportunity to rest and relax somewhat – case interviews are tiring!
Additional tips that I found useful during my interview:
- Consider getting some fresh air and going for walk - it can be a good way to clear your mind before you start again
- Make sure you eat – but not too close to when the interviews start again as you might feel tired post-eating
- Stay hydrated
- Most importantly, if you’ve had a tough case in the morning make sure to put it behind you. Go into your last one with good energy, a smile and a positive mindset!
Best of luck with the upcoming interview.
