Monospace Web Labs Web Developer interview questions

I was initially contacted by Monospace Web Labs and had a brief screening where they asked about my experience and salary expectations. Things seemed to be progressing well, and they invited me for an on-site interview at their offices. However, shortly before the meeting, the interview was cancelled by them, and I was later informed via a short message that they had selected another candidate. No feedback or follow-up was provided, which left the process feeling abrupt and unprofessional.
