This stage is typically managed by a recruiter or HR representative and focuses on your motivation for applying, understanding of Nga’s mission, and basic fit for the role. Expect straightforward questions about your background, organizational skills, and your interest in working with data at Nga. Preparation should include a concise narrative of your career journey, familiarity with Nga’s goals, and the ability to articulate why you are passionate about analytics and data-driven decision-making in a government or public sector context.

2.3 Stage 3: Technical/Case/Skills Round

Candidates advancing past the recruiter screen may face a technical or case-based interview, either in a live panel format or as part of an extended virtual/onsite session. This round is typically conducted by data team members, analytics managers, or cross-functional stakeholders. You’ll be assessed on your analytical thinking, problem-solving ability, and technical skills in areas such as data cleaning, exploratory analysis, and designing robust data pipelines.

Preparation should include well-crafted STAR (Situation, Task, Action, Result) stories that showcase your communication, teamwork, and stakeholder management skills, with an emphasis on how you’ve made analytics actionable for decision-makers.

2.5 Stage 5: Final/Onsite Round
