Pros

Good solid company with great career options

Cons

The forced overtime is why quest diagnotics have a high turn over rate. If you don't work overtime termination will be in your near future.

Pros

Clinical laboratory experience in Microbiology and Molecular. I know the importance of following SOP's and guidelines for laboratory procedures. Aseptic techniques are very important in working with biological specimens.

Cons

I wish that there was more opportunities for day shift positions.
