Bloomberg Software Developer interview questions

I had a phone interview recently with Bloomberg. I have nothing against people that aren't native English speakers or are from different countries, but my interviewer's accent was too strong for me to be able to understand him over the phone. I had to ask him to repeat himself several times for almost everything he said, and after asking him to do so several times I was usually still not able to tell what he wanted to say. I felt bad for him and I think Bloomberg HR needs to prevent this situation from happening in the future. I wasn't selected to move on to the next round, but I wonder how much of that was due to me not being able to understand the feedback my interviewer was giving me along the way. Overall it was a very negative experience - again, not necessarily the interviewer's fault - and terribly embarrassing, probably for both of us.
