The first screening is a HackerRank test. The coding tasks are fairly straightforward; however, you won't be able to access any code documentation during the test, and the online editor can be a bit laggy at times.
If you are successful at the assessment, you will receive a phone call with no prior notification, so make sure to pick up calls from unknown numbers. During this call I was asked if I was available to work at both the Sydney and Melbourne offices, as this was a requirement to move forward with the role. In other words, you have to be willing to relocate to be a successful applicant.
