UST Java Developer interview questions

Applied through employee referral. Contacted by HR and was asked basic questions and he set up a technical interview. In the technical phone interview I was asked few basic questions on OOPs and then interviewer said " Ok from my side". This were his exact words. The technical guy had difficulty speaking and understanding English. After this 1 week passed and there was no response. I sent an email to the HR politely asking for feedback and was told the interview did not go well. Please either have someone who understands English call and conduct the interview or have good communication between HR and technical team. Do not waste someone else's time.
