right sentence to plan a phone interview?

[maxence637]

Hello,
I was wondering what is the right sentence to plan a phone interview with somebody. Should i say:
-Can we call us at 8 o'clock?
-Can we call each other at 8 o'clock? (some people say that each other is superfluous)
- Can we call at 8 o'clock?

If none of these sentences are correct could you tell me the appropriate one?
Thank you very much for your help

Is it convenient for me/us to call you at 8 o'clock?

And if i want to make it less formal such as to plan a phone call to a friend?

Cheers
