LinkedIn Software Engineer interview questions

Sent my CV through their web site. Got a reply a few days later and after a short HR interview they scheduled the first tech phone interview for the next week. I did quite well in the first interview and they scheduled a second phone interview. This time I could barely hear my two interviews and had a HARD time to understand the questions and the feedback. I took around 40 minutes to solve the first question and the solution was quite good. Then I had 20 min to solve the next question. I did it but there was a bug and I could not fix it. 2 days later they told me there was no strong fit and that was the end of the line for me.
