You submit a cover letter and resume by email. The publisher emails back within hours and invites you to "drop by" in the next few days for a "chat." You interpret this as a sign of keen interest. You visit the office the next business day in the late afternoon, as suggested (no specific time was given).
You arrive at 4pm, a few minutes after two other visitors. You sit on the well-worn couch and leaf through the publication. You wait 45 minutes. Finally, you pop your head in the publisher's office and introduce yourself. He looks surprised and asks why you're here. You answer that he invited you, after having received your application by email.
He offers you a chair in his office.
