Second Year Internship
Assessment of the application of safety regulations for all agencies in the Brittany region

"The work environment for a intern is excellent, the atmosphere is good and I have always felt welcome in the various agencies and on the sites I visited.

I have a tutor with whom I review my progress and my impressions on a daily basis, to know if I'm going in the right direction. I can ask any questions I want, I never feel left to my own devices.

Another positive point: I enjoy a lot of autonomy in how I approach my task, I decide which tools to use, and my tutor validates. I learn things every day and I really feel that what I'm doing is useful. A lot of effort is required but it's worth it! "
