Most NAB software engineer reports start with a timed online coding assessment, and several name Codility. One candidate called it the real gatekeeping round. Expect three coding problems under a clock. One candidate said timeouts were heavily weighted, so brute force would not pass. Their hardest problem asked them to split an array into three sub-arrays while minimizing the maximum difference. Another scored above 80% on two easy questions and one medium, including a binary string reduction problem. A React candidate described a two-hour proctored assessment aligned to their stack. One candidate also faced a 30-question cloud architecture multiple-choice section with a 67% pass mark.
The technical round follows the team's stack. A Java candidate was asked about OOP, including the diamond problem. Another was asked about ArrayList default capacity, greedy versus dynamic programming, and Dijkstra's algorithm, and was questioned on the design choices in their projects. A React candidate built a live countdown timer and answered questions on Redux middleware, React Portal and useEffect versus useLayoutEffect. A backend candidate worked through Spring Boot custom beans and property loading. One senior candidate implemented a Stack from scratch in Java and fielded REST API and SQL questions. Another senior candidate had a conversational Zoom discussion that touched SQL, Linux basics, joins and triggers.
Later conversations focus on experience and fit. One candidate described a 20-minute HR round using STAR questions. A React candidate had a 90-minute behavioral session. A senior candidate faced a managerial panel focused on past architecture and system design. Outcomes ranged from offers to rejections, and one candidate withdrew after being asked to retake a round about a month later. Round counts are rarely stated, and the reports that describe a full process show three or four stages.

Synthesized from candidate reports. Individual experiences may vary.
Most reports describe an online coding assessment, usually three problems. Reported difficulty ranges from medium DSA to a mix of two easy and one medium. One candidate said timeouts counted heavily, and a React candidate described a two-hour proctored assessment aligned to their stack. One candidate also reported a 30-question cloud architecture multiple-choice section.
Content depends on the role. Candidates report Java and OOP, Java Collections and data structures, React and Redux, or Spring Boot. Live tasks included a React countdown timer, a Stack implementation in Java and a Spring Boot custom bean. Two senior candidates also mentioned SQL, with one citing REST APIs and another Linux basics.
Several candidates describe talking through past projects and the reasons behind their design decisions. One senior candidate faced a managerial panel of two or three people from the Australian team, followed by a final round with the business and tech head.
One candidate described a roughly 20-minute HR round with STAR-style questions, such as handling a non-performing teammate and responding to critical feedback. A React candidate described a 90-minute behavioral session on experience and problem-solving. Follow-up varied: one candidate heard nothing after being rejected, and another was asked to retake a round about a month later.
