Optimizely Strategy Consultant interview questions

On the day of the interview, the recruiter emailed me 5 min before the event that they're running 10 minutes late. After joining 10 past the scheduled time, I waited another 15 minutes. They didn't show up. I emailed them back saying I have another call in 5 minutes and hence had to drop off. They apologises and asked me to reschedule. The second time, during the re-scheduled interview, I received an email while waiting for the meeting with a cancellation and a note 'sorry for the last minute cancel!'. No further attempts to reschedule happened.
