That we got a complex overview also about the context - for example why do we need some annotations and what they mean. I liked the practical part of the training - having to manually run the commands and call the rest api's
Alina - ACCENTURE SERVICES S.R.L
Course - Quarkus for Developers
interaction through exercises and also projects sharing
Claudiu - MSG system
Course - Advanced Spring Boot
The extra information that was shared, the training was not straightforward groovy, which was nice.
