You don't! Instead you keep applying to other companies.
Having "options" is self-empowering. If you're kicking back waiting by the phone for one company to call you then you're giving them all the power.
Your resume and cover letter should impress them enough to think; "If we don't hurry up and interview this person some other company will hire them." You're selling your skills.
A company hires you because they believe YOU can help them.
