During the training, all modules were discussed in great detail - for two days of training - and that was what I cared about the most.

- I really liked that the entire training was tailored to the level of all users and to different environments. It was cool to see how queries differ in different environments. - A huge advantage here is that the presenter's goal was to share his knowledge with us, and not to show the participants how smart he is:) - I also consider learning from my own and other people's mistakes to be very valuable because it significantly broadens your horizons.

I appreciated Folio's wide breadth of knowledge. Not only was he familiar with the course content, but he also knew of constructs in languages we were familiar with to make examples more meaningful to us. During intervals he shared his knowledge of technologies and solutions outside the training scope to provide insights into other solutions we could use in future (and future training).
