Who’s hiring interns? Where do I look? What should my CV/resume look like?

Since starting college a few years ago I’ve realised that the best career advice for Computer Science students, at least in Trinity, happens between society members, often after some career/industry event they were running.

I learned a lot about getting an internship from listening to students in higher years after DUCSS & Netsoc events, but I didn’t realise that most of that knowledge is (accidentally) kept within their circle.

What companies hire interns? When should you be ready to apply? What should you be doing to be increase your chances? Where do you even look for internships? So many questions, with no easy-to-find answers for most students.
