Pros
Nice international environment and sustainable values at different stage of the business. Many young professionnals, friendly staff. The name of the company can be a real asset on the CV if you want to work in CSR, SRI or any other job related to investment or sustainability.
Cons
There is a huge gap between the recruitment process that make applicants think they are hired for high skills, and the reality of a boring internship without any value added to the work. The truth is you can work as an intern in Sustainalytics without any skills or knowledge because the tasks given to interns are very repetitive, nearly automated, without any responsibility or any value-added. Interns are a mean to build data bases and dedicated to the least interesting tasks, few knowledge or skills are provided. The low salary makes clear that Sustainalytics looks for cheap labour force and does not care about whether the work interns are provided with is interesting or enriching. While Sustainalytics is asking for skilled students and graduated, I only recommend this internship for a short period of time (2 months) and undergraduated students, not for full time interns looking for any responsibility or skilled work. The ethical values promoted by Sustainalytics are not reflected at all in the way interns are considered.
