Once you've effectively researched programs and identified those where you might fit, it's time to apply to and interview with those programs. Your application includes several components, each designed to explain your qualifications and, ultimately, encourage programs to consider you for an interview. Interviews are your best opportunity to tell programs why they should consider you for a position.
However, any missteps along the way can as much as torpedo your candidacy. Luckily, strategies exist to help you present your best self on paper and in person.
