Virtustream interview questions

Honestly this might be one of the worst interview experiences I've had with a company in my entire career. I should emphasize that I was contacted by a Virtustream recruiter through LinkedIn, and that they recruited me for a role. After initial conversations with the recruiter, I was subsequently stood up for a phone interview scheduled with a hiring manager. I never heard back from anyone after, and they didn't even have the common courtesy to write back or apologize. It was extremely unprofessional, and very disrespectful to me as a candidate. I'm quite surprised they're able to fill any roles at this company if this is how they operate.
