What is a bad thing about a traineeship?

One downside of a traineeship is that it often involves low pay or no pay at all, which can make it financially challenging for individuals, especially those supporting themselves. Additionally, trainees may find themselves in a position where they perform menial tasks rather than gaining valuable experience, leading to frustration. Lastly, the competitive nature of some traineeships can make it difficult to secure a position, leaving many qualified candidates without opportunities.
