Spotify Android Developer interview questions

Never got a response.Nevetheless, the date of the appointment reached ( Google Meet Room) and I enter the specified room with the correct code and the recruiter never let me join our meeting . I tried another three times. Waited half an hour and then I closed the application. The calendar was no longer availble ,so I wasn't able to rescedule the appointment from the attached link.
