Pros
The CSO, Dan Voytas, is a highly reputable scientist. Although his ability to influence the quality of science is diminishing as he phases out of the day to day management.
Cons
The company can't decide if it's a breeding, biotech or food company without much competitive advantage in any of the mentioned fields. The management is morphing into corporate style without the necessary resources to back it up. Employees are expected to work start-up hours without the start-up pay (especially at the scientist/RA level), making it the worst of both worlds. With an ineffective upper management, toxic gossip culture, tendency to promote people who are easy to control, the company can no longer attract or retain top talents. If you leave the company to pursue a new career, Calyxt will send your new employer a letter "reminding" them that you have signed a confidentiality agreement with Calyxt, which holds absolutely no legal power but to create a false impression that you may have left the company on bad terms.
