Vervint Software Developer interview questions

First, they gave me a phone call for an interview to talk to me. Overall, the conversation was good, but they told me that the developer intern position was taken. Instead, they said I could apply for a data analyst position, and I accepted. I did not hear anything back from them, so I launched them an email asking them. They did not reply.

After submitting an application, I was contacted via email to schedule a phone interview. After letting the recruiter know a time that worked for me, I never heard back from them, and never got the call at the time I picked. I re-contacted them, and actually rescheduled ANOTHER phone interview, this time getting a confirmation from the recruiter that they would definitely call me at this time. Once again, no call. Very unprofessional.
