Questions

Quick answers

Is this a scam? Will you ask for money later?

No. A Free internship costs nothing: no card, no fees, nothing to buy, and no paywall in the middle. Wartens Ltd is registered in England and Wales, company number 15262249, Milton Keynes. You pay only at our own checkout, and only if you choose the Engineer-verified internship. More in the Help Centre at edwartens.com/support/free-or-premium-internship.

What does the Free internship include?

Four weeks of real tasks with weekly checks and a final exam of 15 questions in 60 minutes, marked automatically, practice in the 3D lab, the AI mentor, and a free Internship Completion Certificate with a QR code anyone can scan to verify it, claimed when you pass the exam. You also get a learning agreement, an ID card, a skills transcript, an attendance record, a logbook and, once you add your college, a credit letter. You finish with the certificate, not with an offer to buy more.

What does the Engineer-verified internship add?

The same internship with people and proof: an engineer's review of every week of your work and your project, the Graded Internship Certificate, the offer and joining letters, the evaluation and project reports, a signed logbook, the college NOC and template pack, and one 20-minute viva call. You also get all 20 Virtual Workplace days where your internship has a Workplace role. The Graded Internship Certificate, letters and reports are signed by Brijin Chacko after the engineer approves. It comes in 4, 8 or 12 weeks (4 or 8 weeks on the newest internships). The price of each length is shown on the page before you pay. In India you can add a stamped or framed hard copy as an extra.

Can I move from Free to Engineer-verified later?

Yes. You can upgrade while your internship runs, and up to 30 days after its end date. Everything you have done carries over, and anything you already paid for this internship in the same currency is taken off the price. You can also extend an Engineer-verified internship later and pay only the difference. More in the Help Centre at edwartens.com/support/upgrade-free-to-premium-internship.

Can I get a refund?

A Free internship costs nothing, so there is nothing to refund. For the Engineer-verified internship, you can ask for a full refund within 7 days of paying if no engineer review has been used; read the refund terms at edwartens.com/refund before you choose. More in the Help Centre at edwartens.com/support/refunds.

Is the certificate worth anything?

We do not claim that any employer must accept it. The free Internship Completion Certificate shows you finished the four weeks, and anyone can check it online with its number. The Graded Internship Certificate in the Engineer-verified internship shows your grade for the whole internship. Certificates are verifiable training records, not an accredited qualification. What carries weight is the finished work behind it. Credit at a college is the college's decision.

Can I do it on my phone?

Yes. You can read the lessons, take the weekly checks and do the final exam on a phone. The labs and notebooks work best on a laptop or tablet.

Is it employment?

No. These are online training internships. You work on a simulated project for a fictional client with simulated colleagues, and there is no stipend. We are not a recruitment agency. The openings listed on the site are third-party listings, free to see and free to apply to, and never tied to buying anything. More in the Help Centre at edwartens.com/support/is-the-internship-paid-work.

Which internship should I pick?

Pick PLC Programming to learn ladder logic and how machines are controlled. Pick Control Panel Design and Wiring to learn how a panel is drawn, wired, tested and handed over. Pick Commissioning and Maintenance to learn safe checks before power, fault-finding and upkeep. Pick Instrumentation and Process Control to learn measurement, calibration and control loops. Pick SCADA and HMI to learn tags, screens, alarms and trends. Pick Electrical Design to learn diagrams, load schedules and cable sizing. Pick one of the AI internships to learn AI for your own field: machine learning, data science, generative AI, AI agents, computer vision, or AI for finance, HR, marketing, healthcare or project management. You can start any of them free.

How long can I take?

Up to 12 weeks, or 8 for the newest internships. Free: the first 4 weeks, which you can extend for a fee, up to the longest length of that internship. The Engineer-verified internship runs 4, 8 or 12 weeks (4 or 8 weeks on the newest internships). Free starts today, and all 4 weeks are open from day 1.

Can I join from any country?

Yes. The internships are online and open to every country, including Nigeria, Pakistan, India and the UK. The Engineer-verified internship is priced in your currency and shown before you pay.

Will my college accept it?

Credit is your university's decision, and we do not claim approval from any board or council. The verifiable documents and the page for colleges help your department check what you did.
