While working on her doctorate, Kober taught at Hunter High and Hunter College and, in 1930, became an assistant professor of classics at Brooklyn College, where she remained for the rest of her career.[5] A former student, Eva Brann, wrote that Kober was "aggressively nondescript....Her figure dumpy with sloping shoulders, her chin heavily determined, her hair styled for minimum maintenance, her eyes behind bottle-bottom glasses snapped impatiently and twinkled not unkindly."[6] On campus she shared an office with four other faculty members and served on standard committees.
