Canals of Amsterdam

No doubt we wanted to meet and mingle with Amsterdam’s passionate developers and invite them to be part of Hack League’s community.

Working with Amazon

For this first Coding Battle, we had to pleasure to team up with one of the most innovative tech companies in the world, Amazon.

After several discussions and brainstorming sessions with their team, we eventually came up with a fun and insightful Coding Battle topic: Chatbots!

Participants would have to use some of AWS’ latest functionalities (Lex & Lambda functions) to make their bots smarter using NLU (natural Language Understanding).

The goal of the battle? Create a movie adviser chatbot. Step by step, participants would make it smarter.
Ultimately, the chatbot would be able to advise you with the best movie to watch. It would take into account the genre you’re in the mood for and the movies that you have already seen. Smart bot!

A final round

For the two best teams, an extra step was awaiting them in the final round: What if I make a typo when chatting with the bot?

The two teams in final could have the help of the rest of the participants for 3 minutes to discuss potential strategies to solve that issue.
After the 3 minutes, each team had 10 minutes to code the solution.

Cherry on the cake: each team had to live code their solutions so that others could see how they were implementing it.
