Swoop Aero interview questions

Was very interested in the company and what they do. However, interview experience wasn't that great. The person who interviewed me was using mobile phone and in an outdoor area, environment was bad, interrupted by noises and his internet was bad as well. Should reschedule with interviewee in this situation, doesn't look professional to me at all and don't feel respect from the interviewer. Mentions that will send me a case study after the interview. However, I've followed up with him and didn't hear from the company anymore.
