This image perfectly pictures my first feelings about the conference, but let me go into a bit more detail first.
I signed up for the Google Testing blog more than a year ago. There I found a lot of interesting and useful reading about the world of automated testing. When I later got an email from Google informing me that there would be a conference held by them, I was not entirely sure wether I should apply. Is it relevant for me? Am I experienced enough to contribute? Well, what’s the worst that could happen? So I applied for it and did not regret it in the end.
