ABB R D Engineer interview questions

I applied online. After one week from my submission, I received a call from ABB HR and they fixed a phone interview for two days later. Then, they called me right at the fixed time and the guy asked me lots of technical questions. However, unfortunately the phone signal was weak such that I heard him with difficulty and also our conversation was terminated several times. I think these affected my interview and did not let me represent myself and my capabilities.
