I applied online. The process took 4 weeks. I interviewed at Deloitte (Dublin, Dublin) in Nov 2018
Interview
I applied at the beginning of October by an online application processes, they immediately asked me to complete online assessments. This was a simulation of receiving messages/emails from various colleagues you may work with and as far as I could tell was assessed based on how you prioritized the messages. Shortly after this I received and email telling me I was selected for an interview. The interview was standard enough, with a few competency based questions. They asked me what I knew about Deloitte, what attracted me to apply for Deloitte etc. It was a straightforward enough interview, no tricky questions.
