MEETYOO Frontend Developer interview questions

I was contacted through an external recruiter. After that my interview was postponed in the very last moment, for a very strange reason, without apologise from their side. That whole conversation had a slightly impolite tone overall. After a third round, nobody ever came back to me and I have invested (and apparently wasted) a lot of time in preparation for 3 interviews, and each interview itself (plus one that didn't happen). This company promises a lot, has big words for themselves, but the values that they've shown are far from what they preach.
