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.

Initial phone screen with CTO, who rushed over a jumbled explanation of the company. He asked me about a project I worked on and then probed further. Although it was clear that my past experience made me an ideal candidate for the role I was interviewing for, I got the sense that he was just going through the motions and trying to get the interview over with. I was then given a code challenge that was not difficult. I triple checked that my solutions were all correct for a number of different test cases. However, I was rejected from the role with no explanation or feedback. Overall, interviewing with System1 was an unsettling and unpleasant experience. I was not treated with due respect through any step of the process.
