System1 Back End Engineer interview questions

Very unprofessional, but typical interview process: phone-screen followed by a take-home coding exercise and a live coding technical interview. During the technical interview, the shared coding website Collabedit went down. At that point the interviewer asked if I could create a shared window on Coderpad. I explained I couldn't, because I did not have a subscription with this service. I then had to explain my solution over the phone and then email my code after the interview was over. Like previous interviewers have noted, my solution was 100% correct (since I still had the code I emailed to interviewers afterwards, and reviewed it for any errors) but was told that that I would not be moving on due to errors on my solution. A complete waste of two weeks of my time--don't bother with this company.
