Building relationships in your field can lead to unadvertised internship opportunities. Attend tech events, job fairs, and social gatherings where you can meet industry professionals. Don't be shy to introduce yourself and express your interest in their company or work.

Regularly check out popular job boards such as Indeed, Glassdoor, and Monster. Also, visit dedicated tech job boards like Dice and AngelList. Internship-specific websites like Chegg Internships and Internmatch can be quite helpful too.

If you have specific companies in mind, make it a habit to check their career pages frequently. Many companies prefer to post internship opportunities directly on their website rather than using job boards.

Keep track of the internships you've applied for, including company names, job descriptions, and dates you submitted your application. This will help you follow up efficiently and avoid any mix-ups.

Being well-prepared for an interview can set you apart from other candidates. Utilize resources like LeetCode and Pramp to prepare for technical interviews. Also, practicing behavioral interview questions can help you articulate your skills and experiences confidently.

LinkedIn's job search feature can be a goldmine for internship listings. Also, use LinkedIn not just to create a professional online presence, but also to connect with people in the industry. Join groups related to tech and participate in discussions.
