Giesecke+Devrient Software Development Engineer In Test SDET II interview questions

Got an online test as round 1 and cleared that. Then in 2 round which was a technical interview scheduled for 1 hour. Now in that round 2 interviewers joined. In mid of interview one of the interviewer's voice was not audible to me but was audible to another interviewer, for which I have rejoined and they too rejoined but problem didn't solved so he started blaming me for this that I am pretending in order to avoid tough question as he was the senior person out of the two. But later interview continued like whenever the senior guy asked any question the other one translated it to me and I answered and this way interview lasted for 2 hours. Although my answers and the java and DSA problem they asked I have solved them correctly but the HR gave me feedback that interviewer said - "The candidate was not ready with the setup and was not properly ready for it". But my opinion is if he was not comfortable with that audio issue from his end not mine, then why he continued upto 2 hours. It was waste of my time as well.
