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.

About The Company

Capella builds trusted space systems that deliver secure, rapid, and actionable Earth intelligence to Amplify Intelligence™ for our allied partners. Powered by IonQ, we're creating the world’s first quantum-enabled Earth observation network, transforming how intelligence is delivered through innovation, speed, and trust. As the first U.S. company to launch and operate a commercial SAR constellation, Capella continues to redefine what’s possible in space-based intelligence. Our taskable Synthetic Aperture Radar (SAR) satellites capture precise, high-resolution imagery in any condition, day or night, through clouds, smoke, or darkness, providing mission-ready insights when and where they’re needed most. We design for the realities of modern defense and intelligence: speed, sovereignty, and resilience. Capella delivers reliable, low-latency data that gives governments and global partners a decisive edge. Our vertically integrated manufacturing and automated tasking platform set the standard for trusted, low-latency SAR operations, enabling faster decisions and stronger deterrence across ISR and national security missions. Together with IonQ, we’re building toward a quantum-enabled constellation that empowers allies to see, decide, and act with confidence in any environment.
