Imprev Javascript HTML Css Developer interview questions

Had a relaxed very positive interview with the development manager. He said it would be 30 minutes and it stretched out for an hour. I passed that interview and was set for an online tech interview. They called me on the phone but had me run their online meeting software. That ran for 10 minutes until someone ran the microwave and the meeting software died. I reconnected but there was no sound which they seemed to blame me for. Rebooted and started working through their online bugs, but it was slow and cumbersome running the meeting software with me running visual studio for javascript development (which they had never used). Worked through one problem and run out of time. I felt they needed to streamline their tech interview process. Their instructions for downloading needed source was unclear and it used up most the ime. I was not offered the job.
