Interviewed recently with a C-5 unit. Consisted of 7 pilots, super casual, no reporting in, interview was online and took about 45 minutes.
1. Introduce yourself
2. Why did you choose to go into the reserves instead of active duty?
3. How do you handle disagreements in decision making?
4. How would you balance a reservist career with an airline career?
5. Do you understand the time commitment involved, even with being a TR?
6. Everyone these days has good stats. What sets you apart?
7. Give an overview of your flight experience. Did you encounter any challenges during flight training?
8. Have you encountered any unsafe situations while flying? How did you handle them?
9. What are your strongest skills when it comes to flying?
10. Do you have any questions for us?
I'd echo Broskees' advice, find a way to tie in your answers to how you'd succeed as a pilot and fit in well in the squadron. Obviously be yourself and answer honestly, but don't be afraid to sell yourself too. Make a strong argument for why you should be the one to get hired.
