Not so Colossal.... - Genome Engineer Colossal Biosciences Employee Review

Pros

Lots of interesting science, and some very bright minds.

Cons

It's weird and chaotic. They randomly lay people off with no reason given. More than half the men who work there are openly gay, so they are clearly violating EEOC guidelines. Their PR team works hard to make them appear like a juggernaut. They truly do not know what they are doing. Genotype doesn't necessarily equal phenotype. They are rushing headlong into getting a species out, consequences be damned. They will kill a lot of embryos that aren't what they intended. They will have to, and that, like their hiring practices, will come under scrutiny.

Pros

Great at marketing things. Some of the original founders (from Harvard) were technically and scientifically top notch.

Cons

The turnover is very high. Most of the initial team (including top leadership and 2nd level leadership) were let go. There is a lot of internal conflict and distrust as a result. There is a lot of hype that is built around some of the work.
