Revolut interview questions

highly disorganized, someone emailed and said they would like me to my availabilities on Doodle which I did, then nothing, I emailed at 9.00 the day of the supposed interview, just to check if we still have an interview as I did not received any interview confirmation. well! no answer, I have tried to call and surprisingly revolut does not have either a RH department ( it's a start up but still), or an office number. I waited for my interview and the interviewer emailed me and said that he was busy at a meeting, and I should book another slot which I did for the next day. the next day, I have to wait 30 min before receiving a message from the same interviewer to check if am still around for an interview. Long story short, they are very disorganize, make you waste your time.
