Pros

Good exposure to the industry, tech, and the formalities in a lab.

Cons

Not great pay No flexible working hours, full time and over-time seems to be expected across all departments. Behind in a few ways, a lot is still done, recorded, and filed on paper, very little digital or automated processes.
