I am afraid no one will be able to provide hard numbers. Also, this is office and company dependent - some consulting companies have been hit harder by COVID in certain regions.
On the other hand, I know people who could not proceed further with an office in 2020 as the office was not hiring anymore due to COVID – they asked them to continue the process with another office if interested.
I haven’t heard this happening in 2021 so far, which hopefully means things are getting back to normal. Although this could also simply mean companies understood their real demand needs and are planning better the recruiting process.
