I have just checked their website and seen they operate a rolling recruitment. The deadline is May 31st, but since
@futuretraineesolicitor mentioned success with submitting quite close to the deadline, it’s worth a shot. It’s always better to submit a quality application, than a rushed one. I’d still say to try and submit it quite early on before the deadline though.
Best of luck with the app, I know you’ll do great. Feel free to let us know if you have any more questions before submitting!
