Pros

There are a lot of pros. The management is amazing, the colleagues as well. The culture is very welcoming and everyone is happy to help out. There is amazing work-life balance, you don’t have to think about work after the working hours.

Cons

There have been some issues with the workload some colleagues take on, and others don’t, I believe it’s a management issue tho and if they are made aware, it could get better. The opportunity to grow and get better pay is like in most CROs - it happens slowly and with not a big of difference in the salary.

Pros

Getting to work with major pharmaceutical and biotech companies and on important and global research studies.

Cons

If the company starts to dip financially at all, your job may be on the line even if you were a top performer.
