Pros
Having worked at Evidera for over 4 years, the one thing that nobody can deny is scientific quality and expertise of the team members throughout the business. Although many people have left, there are still some high quality staff there. The scientific reputation of the business is strong and the salaries are among the best in the sector, although you can get more if you go to pharma. You will be able to learn a lot and grow from your time there, especially if you want to develop strong technical skills.
Cons
Over the years the culture became more and more toxic with a total disregard for employee wellbeing and human decency. Blame culture is not only rife, but is top down from the very top of the business. The targets set are totally unrealistic and senior leaders will happily throw anyone they can under the bus and shift the blame when it inevitably comes due to missing targets. Work life balance is non existent and you should expect to work long hours. Don't expect management to treat you like a human being, you're just there to make as much money for the business as possible.
