It is in this house that I was born. vs It is in this house where I was born.

Hey, I have two sentences, which one is correct?
It is in this house that I was born.
It is in this house where I was born.
And my teacher asked me to find one mistake in this sentence:
This job suits students whom want to work during holidays.
Thank you very much.:D

Thank you very much
But why do we use "who" instead of "whom"? "Students" is an object so I think we must replace by "whom":-?

.
The case in the subordinate clause takes priority: 'who want to work'.
