As one of the answers mentioned earlier, your school's career service office would be a great resource.
I'd also recommend you (if you haven't done yet) starting your LinkedIn journey and follow industries and companies that you're interested in.
You can take the following actions on LinkedIn to open up more avenues for your future:
- Follow industries.
- Follow influencers.
- Read companies' vision statement and specific solutions in their industry and assess if you could associate your needs and future with them.
- Start following recruiters within the companies you like - they sometimes post internship openings before they are posted on corporate websites.
Some companies are not too active on LinkedIn, try checking their career postings the corporate websites every other week - set up a reminder on your calendar / phone so you won't forget checking back.
