either clause- preposition must?

[Kumar Nadimuthu]

Interview will be conducted either in Mumbai or in Chennai.

Does it work without underlined preposition in "either" clause?

 

[SoothingDave]

You need one "in" at least.

You could say:

"... either in Mumbai or Chennai."
"...in either Mumbai or Chennai."

Or your original sentence.

 

[Rover_KE]

The sentence should begin 'The interview will be conducted...' or 'Interviews will be conducted...'
