eCourier.co.uk interview questions

What a nightmare! One of the most unprofessional encounters while job searching. The interview was rescheduled 1 hour before the call and the POC suggested an alternate day. I agreed but there was no call link or anything. I followed up 1 day before the meeting but the interviewer emailed back on the day of the meeting with 4 time slots and i chose 1 time slot. Guess what neither they reverted with the call link nor they replied back. Highly unprofessional and wasted 2 days of mine without turning up to the interview.
