Testimonials from 2022 trainees and a mentor

Junior Developer

“I was very satisfied with the internship, it provided me with an opportunity for self-realization, which was very important to me. I not only gained a lot of knowledge and practical skills but also made many valuable acquaintances and got a permanent job. I also love the office in Tartu, as it is cozy, modern and small enough so that everyone knows each other well.”

Roberta, Junior Developer

Junior Developer

“The internship at Wisercat was a valuable experience for me, the expectations met the reality. The friendliness and supportive attitude of the team helped me get the most out of my internship experience. By working in a real project, I got a good overview of the job as a junior developer and the challenges associated with the job. The internship provided an opportunity to use my previous knowledge and learn new skills at the same time.”
