What will I learn at the Telerik Academy Upskill Data Engineer program?

Three months of Data Engineer training packed with real-world use cases and methodologies to help you manage the Data Engineer process from the get-go. By the end of the program, you'll have developed expertise in key data engineering components, including data ETL, warehousing, and modeling. You'll have built a strong foundation in Python and a deep understanding of SQL, command line, MongoDB, and Git. You'll also have learned how to design and build data pipelines, streamlining data movement and processing.

Who can apply and how?

This training is designed for software engineers seeking to leverage their engineering mindset in data-driven enterprises, data analysts or data scientists aiming to grasp the end-to-end pipeline of data-driven products, novice data engineers looking to enhance their skills, computer science grads or students interested in industry-relevant proficiencies, and companies keen on upskilling their workforce to thrive in the data-driven era. You also need to be 18 years of age or older. The admission process includes the following steps:

  • CV and application form submission (mandatory)
  • Online Data Engineer test (mandatory)
  • Online career event (optional)
  • Interview (upon request)
Do I need any previous Data Engineering experience?

No, prior Data Engineer experience is not required. Our training is designed for individuals ranging from software engineers to data analysts and even those transitioning from computer science backgrounds. Whether you want to leverage your engineering mindset or grasp the end-to-end pipeline of data-driven products, our program suits diverse learners.

Can I choose between online and onsite training?

The program will be held online. Please note that attendance is key to our students’ successful graduation. Participants must attend all classes. Up to 3 days of absence are allowed, plus the program has 2 vacations (3 weeks in total).

How much does the training cost and what are the payment methods?

The tuition fee for Telerik Academy Upskill Data Engineer is BGN 4 700. The fee could be either covered by you or your employer. In both cases, the fee is paid via bank transfer prior to the program start. Another tuition fee option is to pay in installments with a loan from a bank, partner of Telerik Academy. You can benefit from a deferred payment over 12 - 24 months’ period.

Do you offer discounts for the NGO (Not-for-profit) sector?

Every candidate working in the NGO sector can apply for a 90% discount off the regular program pricing (two per cohort). The candidate must submit their application through our website (www.telerikacademy.com) and follow any specific requirements for candidate selection (submit an entrance test, attend an interview, if requested, etc.). If the candidate is invited to join the program, their employer will be required to sign a contract with Telerik Academy and cover 10% of the regular tuition fee for the program. Please note that the candidate selection process evaluates the candidate’s profile, not the NGO’s.

What does the online test include?
The entry test assesses the candidate’s skills when facing common data engineering problems and technical implementation. The test also establishes the candidate’s minimum technical knowledge in fundamental data engineering areas, such as SQL and Python. The deadline to finish the entry test is 5 days after you have submitted your application.
What is the candidate selection process?
We use a holistic review process when evaluating applicants for admission. The final selection of candidates is not based on a simple formula of grades and test scores. Instead, we consider a variety of factors: application documents, online data analyst test results, personal motivation for applying, etc.

Some candidates might also be invited to attend an interview to additionally discuss their motivation and aspirations. Interviews focus on candidates’ motivation and aspirations and determine if the program is appropriate for each candidate based on their needs, expectations and experience.
What is the length/cadence of the program? Can I balance it with work or studies?

To get the most out of the program, you’ll need to immerse yourself in it for 3 months. To recharge your batteries, you’ll have 2 weeks of vacation. With classes 2 nights a week, this most complete hands-on Data Engineer program makes it possible to also balance work or other responsibilities.

What does “two-week trial period” mean?
If you drop out of the program within the trial period, which is in the first 2 weeks of the program, you won't pay any tuition.
Does Telerik Academy help alumni find new jobs after successful graduation?
As this is an Upskill program, it isn’t geared towards connecting learners and businesses. But the skills and experience you gain will help you excel in your career and/or find a new job, just like it helped our alumni reach their career goals.
