I started with an online application after connecting with people who’d been through the bank. Before the interviews, I completed a Koru personality test, and then the recruiting path moved to a phone screen where the conversation was mostly about fit with some basic technical touchpoints. That part didn’t feel like a technical grilling so much as a check that I understood what I was getting into and could explain my motivation clearly.

Up until the final interviewer, I felt like it was going well—most of the conversations skewed behavioral, and I stayed focused on my experience and how I’d fit the role.
