Could you please provide your contact information, so that we can schedule an appropriate date for an interview? A more natural, less formal way? Can you give me your contact info, so that we can set up an interview sometime next week? What is your contact info? I want to set up an interview with you next week. Would you mind writing down your contact info? I want to set up a time to meet with you for an interview. It depends on what you are trying to say.

You could say: Could you provide your contact information so we can reach you to schedule an interview? - "give me" would not be appropriate in a formal context, which I think is the case here. - If the speaker is representing a company (the Human Resources dept, for example), "we" is much better. - "to schedule an interview" is my guess as to the most likely scenario. If not, be specific with that other situation.

So I can reach you.....
