I was impressed by the flexibility of the speaker, who adjusted the program to the needs of the participants.


The speaker approach was extraordinary as it did not create barriers between the participants and the leader, which I consider the great advantage. What is more we had no concerns with asking questions as we were encouraged by the speaker.

Possibility of gaining practical knowledge.





Excellent response to students, great involvement in sharing the knowledge and motivation to learning. I loved the practical examples of true “tester's life”. I appreciated the patience in responding to all our questions, even those not connected with testing but the general IT business line.

Working on Jira and Testlink – learning the tools and practical use was the most important for me.
