Alltech Consulting Services Junior Java Developer interview questions

MOST UNPROFESSIONAL COMPANY There was no interview process. They emailed me 3 times to schedule an interview, each time I response and they don't reply to me after. When I managed to schedule a screening call the recruiter didn't show up! I managed to schedule another call with a different recruiter but she also didn't show up!! They never responded to any of my communication! This is the most unprofessional company I have ever dealt with!!
