Really sorry for any misunderstanding here - there was an assumption made on our behalf that given this specific role was for a Senior Rails Developer then the technical task was to be completed in Rails and the candidate would have that as their preferred framework, but we definitely should have made that clear in the task spec and have now altered the wording to reflect that.
As for the office being busy - that's because we ask anyone who's local if they're able and happy to, to come in and meet the candidate in person and have lunch with them. We like for you to meet a good selection of us so you get a better sense of the team you'd be working with and ensure we're the right team for you, as much as the other way around (we do also have candidates speak to members of the team working remotely on video calls throughout the day, too).
Apologies again for any miscommunication or misunderstanding on our behalf - obviously not how we want the team and tech day to go!
All the best.
