Prior testing experience can be advantageous, however, the specific experience requirements vary depending on the type of testing involved. For instance, in functional testing and localization testing, we typically validate the necessary skills with certifications or relevant courses. Nonetheless, we are open to individuals with no prior experience in software testing and provide opportunities for them to join our team. Additionally, we offer comprehensive courses to equip all team members with the knowledge of the Testlio process, standards, and testing capabilities we offer.
