T-Mobile interview questions

I applied for DS role at T-mobile, Seattle through a recruiter I know. I received a call from T-mobile HR after a month and he scheduled an interview with Hiring Manager for the next week. He said, I have to speak nice to the manager and my english should be good and clear. He said Hiring Manager doesn't like any accents and he is feeling it from my voice which might be because am from east coast (but I clearly understood he said it's because am immigrant and I have accent). I did not like what he said and lost interest for that position. I received a call from Hiring Manager at the scheduled time and I cannot hear him clearly, seems like he is far from the phone and phone is on speaker. When am replying to his questions, he is asking me to speak loud and it was very tough to hear him. I am annoyed after 10 minutes and I just started to speak continuously about my education, experience for 10-15 minutes and asked him if he wants to know anything else. I know it's not gonna work out and am not interested to work with them at all. Then he said about their work culture for couple minutes and asked me to talk to the HR after couple days, I never called them and never heard back from them.
