I was all set up and ready for our video call twice on Friday and was disappointed to see that they did not show up to either.
I did receive their voicemail after our second scheduled video call, but by then it was much later and even in that voicemail, you asked to reschedule for next week. I understand that they have a busy schedule, but I'm not particularly impressed by your lack of professionalism, or by being left waiting twice in one day without so much as a confirmation email or cancellation/rescheduling email before our scheduled video calls.
For those reasons, I chose not to reschedule our interview with Randstad.
