Campbell North interview questions

I saw an ad for this company for a technical recruiter position in Toronto, Canada. Although I don’t see any location in Toronto, the person who emailed me was listed on the company so it seemed legit. He scheduled a phone call and he was to call in from NYC. I waited for the call and got an email from him saying he would be late but asked if I would be free after a certain time, which I told him I was. I waited for that call all day and all evening and no calls. Two emails later no reply. Horribly unprofessional, if you are not interested anymore then an email would suffice but I received no contact again despite sending several emails. Sounds sketchy and scammy, stay away!
