Pros: flexible work schedule, learned a lot, nice coworkers
Cons: weekend work, unexpected change of schedule
Learned how to do many tasks, such as create buffers, clone bacteria, create mutants using electroporation as well as create primers and purify protein.
Tasks changed based on current projects and availability of coworkers. I worked in a small lab, but learned a lot.
Work hours were flexible, but coming on weekends was semi regular.
