Hey I applied last year also and received an email saying to let them know if I am still interested within 3 days and that assessments are being held over the summer with Autumn start dates etc. It wasn't an invitation to assessment though. Is this the same or a different email?
What stage did you get to before? I wasnt offered an interview before as they stopped recruiting so not sure whether the email implies I will have an interview or not. Slightly confused :/ x
