The interview process at Izertis is structured to evaluate both your technical competence and your suitability for specific client projects and internal teams. The journey typically begins with an initial screening conducted by a talent acquisition or human resources professional to verify your background, language skills, and core qualifications. Following this, you will progress to technical evaluations or discussions with project managers and technical leads who oversee the specific domain or client account you are targeting.

Depending on the nature of the role—especially positions tied to public administration or specialized external client contracts—the evaluation flow may involve multiple layers of approval and validation. The pace can vary significantly based on administrative requirements, and the process places a strong emphasis on verifying documentary credentials, professional history, and domain alignment. Throughout the stages, interviewers focus heavily on whether your practical experience matches the day-to-day realities of the project.
