I was going to post "not normal at all", but then I noticed you mentioned recruiters. Are these 3rd party recruiters you are going through (i.e. not employed in-house by the companies)? If so you might want to consider the possibility that the recruiter is claiming to have scheduled an interview that the company hadn't really properly agreed to or were pressured into.
But in general when dealing directly with a company I'd say: no reply to an application is completely normal, but not turning up to scheduled interview is not at all.
