Personally I really enjoyed the whole experience. As it was my first time attending a Test Bash event I was a little nervous (as I can be painfully shy sometimes), but everybody’s welcoming and friendly attitude made it so worthwhile.
The pre bash meet up was good, great location, lovely office. Arrived at almost the same time the Pizza did (though I can’t eat the stuff, damn evil cheese allergy!) Met some interesting people at it.
The Bash itself I thought was very well done. Everything on the day from my point of view seemed to run very smoothly (might be different from your prospective). Speakers were great, personal favourite was Gus and his perpetual motion style of presenting. Venue was a good choice though, had a good size stage, and also an area away to mingle during breaks.
Downsides, as you mentioned the Wifi, but unless you went around the whole building beforehand testing with 100’s of connections it there was no way of knowing that would have happened. And even for a tester that might be excessive Disappointed that I had to leave early to catch a train, as I missed the 99 second talks and the post Bash meet up. Won’t make that mistake again.
So basically, thank you all for an amazing experience, you did an amazing job. Dublin will have a lot to live up to.
