Received this response last week (Feb 3rd) from the department:
"Thank you for your interest in the Clinical Psychology PhD program at Harvard. Faculty are currently reviewing applications and conducting interviews. Interviews (whether via phone, Zoom, or in person) are always part of the admissions process for our eventual admits, but not all applicants will receive an interview. We expect interviews to take place through mid-February. Admissions decisions will be sent out in early March."
