Notes for the report


The figures were captured from the career sites of the below firms between 1st July – 30th September 2021.

It’s worth noting that not every firm posts all of their open roles on their career sites so the actual activity and/or number of live roles may be different. This report only seeks to analyse the publicly available information.

We will also caveat that just because a role was removed does not necessarily mean that it has been filled although it’s reasonable to assume that if somebody has taken the time to upload or remove a role there is a reason behind it.
