Hopefully you have had a chance to start the first 7 days of this great event. The challenges are getting progressively harder as they said in the beginning.
I have no experience with NoSQL databases and the room that I just got done with is talking about NoSQL databases, specifically Mongo. The room goes into how to SQL inject the databases in order to bypass login pages and different search queries.
I can't wait to see what else is coming from the great team at Try Hack Me. As always if you have questions or concerns email me at firstname.lastname@example.org
