Sponsor.Online interview questions

The first round was though Skype which went smoothly and there was no specific question. They booked the second round but the day before interview they sent an Email and they said their boss went abroad and they have to cancel the interview and they will reschedule the interview but they didn’t after a week I wrote them and asked them if we can reschedule, They didn’t reply to my Email for a whole week and then they said that the positions are filled! More looks like a scam!!
