Application Process


Dimitar T.

Thanks to Adastra’s Internship Program, I received first-hand experience in ETL testing, BI testing and various tools which I was not familiar with before. This experience is so beneficial for me because I got to see the communication path of a real QA team and how the professionals work in term of skills and ethics. I am happy that I had and have the opportunity to see how real-world projects are being carried and to be part of something big.
