This role requires working on-site with a TS/SCI clearance and plays a crucial part in advancing mission support and decision-making for intelligence operations.

2.1 Stage 1: Application & Resume Review

The interview process for the Data Analyst role at DarkStar Intelligence begins with a thorough review of your application and resume. The recruiting team and hiring manager will assess your background for relevant experience in data analysis, analytic methodologies, and security clearance credentials (TS/SCI with CI Polygraph). Emphasis is placed on technical proficiency with tools such as Tableau, Excel, Python, and SQL, as well as your experience with workforce analytics, database management, and data visualization. To prepare, ensure your resume clearly demonstrates your analytic skills and highlights your experience with large, complex datasets, dashboard creation, and communication of technical findings.

2.2 Stage 2: Recruiter Screen

Next, a recruiter will conduct an initial phone or virtual screening to verify your qualifications, discuss your interest in DarkStar Intelligence, and confirm your active security clearance status. This step typically covers your motivation for applying, your fit for the organization’s mission, and a high-level overview of your technical and analytic background. The recruiter may touch on your experience with data integration, survey support, and communicating insights to non-technical stakeholders. Prepare by articulating your alignment with the company’s values and mission, and be ready to summarize your analytic experience and tools proficiency.
