The last conference in 2016 for me was SQA 20 in Belarus. It was 20th anniversary with special English day before the conference and many english speakers were invited including me. We had a lot of fun with other speakers and most of their presentation were high quality and interesting topics.
I shared my first speech with second speaker because we both submitted similar topic – Are test cases dead? I had mixed feelings about this one. But I definitely enjoyed my second speech about Transition from Scrum to Kanban – I had 1.5 hour slot so enough time to go to details and I spent another hour after talk answering questions – that is benefit of having lunch break after the talk
