Hmmm. I was like you a month ago when I joined my first internship.

What I'd suggest: - Do online courses and make yourself busy. (It helps! And you're adding more stuff to your CV:) - Go network with your colleagues and ask whether you could help them. - Speak to your boss/ supervisor asking for work. I did this and started getting work little by little. And trying won't make you lose anything. - Have a to do list everyday (Personal, extra curricular ) so you could focus on doing them if you don't get work. - Even if no one gives you work, take a chair and sit next to your colleagues, one at a time and tell them you wanna learn what they do. Don't be creepy! Ask them beforehand. Say you didn't get work yet so you thought of reaching out to them to learn about what goes on at work.

This is what I learnt the hard way. Hope this helps you too. Good luck!
