Ventajas
Quantum dots look pretty under a certain light. Nanoco has connections to University of Manchester as it was a spin-out from the uni. So if you are a University of Manchester graduate it will be easy for you to get a job there (only a pro for UoM graduates).
Desventajas
Unusually high proportion of employees leave each year. Don't apply to Nanoco if you're a young man - Zero promotion opportunities for young male employees. No men under the age of 30 were given a promotion during my time at Nanoco. Don't apply to Nanoco if you're a woman - Very few women at senior management or director level. Senior men seem to enjoy promoting young women to become their direct reports, and they get no promotion opportunities after that. Be careful.
