Newpage Solutions Webmaster interview questions

I was contacted through LinkedIn and asked if I would like to interview for this position of webmaster. I agreed and first interview was with recruiter. The second interview was with the team manager I think, and the third one was with developer. Here is when things became interesting. I was asked various development questions and I knew many of those...Html and css..and then came JavaScript question that blew my mind...they asked me do I know about generators...I mean, I know senior developers that don't know what generators are and yet I was asked that question for webmaster role. After that I received a message I was shortlisted and that they will forward my application to client company to choose. After that ghost town..they didn't write to me and after a month I asked what is happening and they said position is on hold and they will contact me if there is an update. They contacted me again and asked if I am interested and I told yes, and one more month passed and again they are saying that position is on hold. This is not serious company and they just waste people time. Keep that in mind if you are contacted by them.
