The interview process for a Data Scientist role at Pra Group is structured to assess both technical skills and cultural fit within the organization. The process typically unfolds in several key stages:

1. Initial Screening

The first step in the interview process is an initial screening conducted by a recruiter. This is usually a phone interview where the recruiter will discuss the job requirements, your resume, and your background. The goal of this conversation is to gauge your interest in the role and to determine if your skills align with the needs of the company. Expect questions about your career goals, key strengths, and any relevant experiences that demonstrate your fit for the position.
