I worked at Environment Agency (More than 8 years)
People (in the main) are very passionate about what they do.
Benefits are great.
Pretty good work/life balance
Interesting and varied work
There was a lot of change, continuously.
Advice to Management
Have a clear vision, embed changes then let things settle and review.
Don't leave those who are the top employees to do 90% of the work
I applied through a staffing agency. I interviewed at Environment Agency (Shrewsbury, England (UK)) in March 2017.
Competency based interview, (5) followed by lab based test. Friendly relaxed process with guidance and support on structure of answers. Time allowed to add anything else that you feel would support your application.
Written application and communication via online agency portal is straightforward, although slightly tricky due to low word count requirement on competency answers.
