Wood Mackenzie interview questions

Received an invitation for a dial in conference interview, few weeks after this interview received an invitation to complete an online numerical reasoning assessment which I completed. A month later, received an invitation for a face to face interview on a specific date where I replied asking for another date due to a work commitment, they scheduled an interview on different date then they cancel it at the last minute. A month later received an email saying that "we regret to inform you that your profile is not suitable for this particular vacancy".
