Got questions?
How long does the course take?
It's up to you: there are no fixed deadlines, nor limits on how many hours a day you can study. See course program for more details.
What's the difference between full-time and flex courses?
Both tracks have identical programs and aim: to get you a job. The only two differences lie in schedule and payment form. Full-time courses are free until you get a job in tech. Henceforth, you pay a percentage of your salary, per agreement. The schedule is from 9 am till 6 pm Monday through Friday. Flex courses, on the other hand, offer a fixed price and an instant access to all resources. You study at your own pace with the support of our experts, under the same employment guarantee.
Will I receive a certificate after completing a course?
By all means! Our 3,000+ graduates use them on LinkedIn and other socials, but... it's just a bonus. We are rather focused on getting you a job in tech.
What's the course schedule?
Flex tracks allow you to study whenever you like to: watch pre-recorded lectures, solve interactive tasks, and submit questions to our mentors. They respond during work hours. The only regular events are group Q&A sessions, taking place 2 to 6 times a week. We hold them in the afternoons or evenings, not to collide with your plans.
Can I apply if I don't have a background in tech?
8/10 Mate students don't have any experience in tech. But if this doesn't reassure you: our courses cover even the most basic topics, and our team is always ready to provide support!
I haven't turned 18 yet. Can I apply?
Yes, you can apply at any age. The employment guarantee works if by the end of the course you are of legal working age in your country.
I'm over 50 years old. Should I apply?
We educate people of all ages, besides: it doesn't matter in tech. And if you worry studying might be too much of a challenge... there's no substance to it! If you stay engaged, you'll graduate the course and find a job in no time :)
What kind of job will I be able to get after graduating from the Web Development course?
Our Web Development graduates usually land their first jobs in the following positions: Frontend Developer, Junior Frontend Developer, React Developer, Vue Developer, React Native Developer, Frontend Developer (Angular), and Frontend Developer (HTML, CSS, JS).
Do you guarantee employment?
Yes! In case you complete all the required learning modules and do not receive a job offer within 16 weeks of active job search (with our assistance and advice), you are eligible for a full refund.
How many graduates get employed?
80% of full-time Mate graduates go on to work in the tech industry. As for flex graduates: everyone who wanted to find a job, succeeded.
Where will I be able to find a job?
We teach and employ worldwide. At the moment we have students, graduates, and colleagues in Europe, Asia, Africa, the USA, Canada, and Australia.
How do you help graduates land a job?
Our HR specialists assist you in the process. They help you prepare CVs, cover letters and profiles on professional social networks, find relevant vacancies and prepare for interviews.
