How to get into a company where you can do an internship (the city of St. Petersburg)?

Question

IT education

Let's take the superjob site as an example: there all internship/practice ads are designed for senior university students, and I am a 3rd year college student. It is not clear where and how to look for a company that can accept you for an internship. If someone had a similar situation, it would be interesting to hear how you did
There is of course an option to go for an internship in a company that the college offers, but this option does not suit me
