RDX Works interview questions

I had 2 interviews - the first with HR and the second with UX. Both times I got short notice interview times. HR said they made half the UX team redundant 6 months earlier and were now hiring again. That made me uneasy. After two interviews, no one ever got back to me about the job status. I hate leaving things hanging so I followed up and they never replied. There were several red flags about this company and I can only imagine how dysfunctional it must be working there if they can't manage a quick 'no thanks' email to interviewees. Can't say I've dealt with a more unprofessional and discourteous company in an interview process.
