In general, not only the content of this internship was wonderful, but also Lucia and Lalita were always helpful during the process. Based on my experience, three points are remarkable.
① One of the most important thing that I have hardly seen in others' review, is that TIG can help you arrange the graduation internship required by some European University, which usually requires a third-party contract (you, internship company, and university). This is incredibly useful for some students to conduct international internship without working permit. I deeply remembered how helpless I was in the beginning when I searched for international internship as a non-European student at my university. But anyway, TIG help me make it possible.
② You should always take the initiative to reach out to different team-mates, not only because you might work in a very different culture, but also you probably can't Spanish in the beginning. If you are open and professional enough, your colleagues will be more than willing to help you.
③ You should know what's your priority during this internship. I know some people just want to have some international experience. My priority is to utilise this internship to achieve my academic goal (writing a sound paper) and professional goal (worked on a digitalisation project for a large captive company). So I don't pay a lot of attention to socialisation :(
