Initial Screening Round

If your CV makes it past the initial review, a recruiter from Chubb will contact you for an initial screening call. This call often verifies key details about your experiences and skill level.

• Discuss your favorite machine learning algorithms like SVM or logistic regression
• Share your experience with data imputation, data analysis processes, and specific libraries you’ve used

This round will also include questions that assess general programming knowledge and your problem-solving abilities in technical scenarios.
