How often are new jobs added?

New internships are added continuously throughout the day. We monitor company career pages and hiring tools in real time, so most roles appear on InternshipsHQ shortly after they’re posted.

Why can I only view a limited number per day on the free plan?

The free plan is designed to let you explore the platform and see how fresh the listings are. Limits help us prioritize serious applicants and keep the signal high. Pro removes these limits and gives you full access.

What sources do you pull internships from?

We source internships directly from company career pages, startup hiring platforms, and applicant tracking systems like Greenhouse, Lever, Ashby, Workable, and others. This helps us surface roles earlier and avoid repost-heavy job boards.

Are these internships legitimate?

Yes. We actively filter out expired, duplicate, misleading, and low-quality listings. Each role is checked for legitimacy and posting freshness so you’re not wasting time on dead or fake opportunities.

Can I filter by location, experience level, remote, or salary?

Yes. You can filter internships by role, location, experience level, remote or hybrid status, and pay when available. Pro users get access to more advanced and saved filters.

Why are early alerts so important?

For internships, timing matters more than volume. Most callbacks happen when roles are still new and applicant pools are small. Early alerts help you apply before listings get flooded.

Do you show salary or pay information?

When companies include pay information, we display it clearly. Not all internships list salary upfront, but we prioritize transparency whenever the data is available.

Is InternshipsHQ suitable for senior or experienced roles?

InternshipsHQ is primarily built for internships, entry-level, and early-career roles. If you’re looking for senior or leadership positions, you may find limited results here.
