If you enjoy layoffs, excessive overtime, and management abuse, Ciena is the place for you. - werkgeversreview Director of Software Engineering bij Ciena

Ciena goes through regular cycles of mass layoffs and outsourcing. Heavy overtime is expected, software in particular is abused and opportunities for advancement and learning new technologies are limited. Software engineers can do much better elsewhere. Software engineering management jobs are even worse: despite much lip-service paid to good management practices, management at Ciena is insanely political; managers are expected to leave their conscience at home: ride staff hard, burn 'em out, and then lay 'em off.
