The interview had been confirmed for 2pm by email. However, at 1pm on the day of the interview I was sent an email saying : 'no need to attend the Teams invite- it was only sent in order to provide the link below.' The link was to an excel file in SharePoint in the web browser to complete an exercise which I had only about an hour to complete and luckily I had checked my email as the interview time was changed to be at 3pm.
