mobiManage .NET Developer interview questions

Apply through career site of university. HR contacted and scheduled the skype interview. Interview was schedule with three people from engineering team. None of them available on scheduled time. After being 30 minutes late, one of the engineer contacted me on skype call. He was talking from Mexico. So much disturbance. Not able to clearly understand what he was speaking because of it. He was expecting that candidate should have an work experience of all the developement tools they are currently using at company with same version. Very unprofessional people. Recruiter doesn't care to reply follow up mail. Complete waste of time. Advise - ASU students stay away from this company.
