will it have a big impact on the recruitment?
Hasn't for the last 7 years, so far.
To all those out there waiting to get in, there has been a lot of office politics for years. It is bad that this has affected you all. The actual ATC side has not had a lot of input into who is actually selected for a loooong time.
This has changed in the last few months, and about time. Actual ATCs have been included, in a positive way, in the testing. The people I know who have been a part of the testing phase are experienced ATCs, and seem (unusually) confident that they are now involved in selecting people who show an aptitude for doing ATC.
If you are selected, best of luck, work hard and you'll get there. If you don't know something or don't understand something, ask.
In Aviation in general,be it ATC, pilots,engineers,etc, we have the most finely sensitised BS detectors. We know when you don't know, come clean and we can help.
