Monospace Web Labs 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.

I applied through the company's website. The owner send me an e-mail for the interview arrangement. Although I answered the e-mail I did not receive verification that the interview would be completed. I waited a whole day for the verification and at the end of the day I received an e-mail for interview reschedule. The owner did not apologize for the delay or explained why he was so late to answer. Of course I did not arrange a reschedule because obviously the owner could not be trusted.
