VIPRE Security Product Marketing Manager interview questions

Multiple phone interviews before a person to person interview with the Director (direct manager). Then additional phone interviews with the team I would be working with. After 5 interviews in total, the company went completely dark...no communication whatsoever. Finally gave up after multiple attempts to just get an answer from them (to multiple HR contacts, to the director). Incredibly disrespectful and unprofessional behavior. Feel like I unknowingly dodged a bullet by not getting an offer. Do not waste your time here - not for someone that values integrity.
