Professional Access interview questions

It was a telephonic interview. 2 guys were on the other side of my phone. 1. Questions were very vague. Like how do you configure this/which option do you select to achieve this. Basically I did not understand most of their question. Then I lost interest in answering their questions and responded disinterested. 2. Always interrupting while I was answering. Not a professional gesture.

Initially interview started with technical round, later the manager round. the HR management play with the peoples who have cleared all the rounds they are not sending a confirmation call or email. they will play and make a waste of time during interview. so prefer never go for this company. worst interview team. dont have proper skills to take an interview
