The interview takes place on Sparkview... If you lose your connection, there is a very good chance that you will lose your opportunity to interview. The questions are based on 6 questions... video chats where they ask irrelevant questions to the role you are looking at. The timeline they give you to interview is irrelevant. They will cut you off at any time, so be prepared to interview as quickly as your connection allows... but most of the jobs are already taken and I think they are just doing the interview process for show.
