Hello Bruno González, I know of some websites where companies are looking for students for internships. Once you are in the portal, you will see the offers with a short description of what they are looking for. I attach here one of the pages, if you like it but you don't find any offer, don't hesitate to ask me again. Best regards. (https://www.coie.upm.es/#)

Thank you for your answer! I am also looking for this. I would like to clarify how you combine studies with engineering? When I was writing my final paper, it was quite difficult for me to decide on the topic, but my work helped me with it. Then I checked the work for plagiarism here: https://lettersaboutliterature.org/ and passed it successfully. It was not easy, but I would like to ask if there are any other ways to do it? How do you cope with combining study and work?
