I conducted this talk three times:

1. IT Happy Hours, Czestochowa University of Technology, 03.04.2014 (Fb event),
2. SKN IPIJ (Students organization), Silesian University of Technology, 10.04.2014 (event),
3. Private talk, 29.05.2014

Here is very first version for this talk (used even before first version described in this article during some my academical experience).

Whole talk is basically about communication problems between developers and manual testers. Also this talk covers topics about how to prepare yourself and what traits make a good tester.
