Case Behavioral Technical
The final round for this internship involved three stages. It kicked off with a case study. Following that, there was a behavioral interview, covering standard questions you'd tackle using the STAR method. The last stage was the toughest, focusing on machine learning and statistics, so you really needed to grasp the fundamentals of stats.

Technical Coding Case Behavioral Presentation
The steps of the interview process were pretty organized and it didn't feel like too much. However, the recruiter was kinda cold and didn't respond much. The main interview day was different than what was described; the ML part turned into a business case study, and the business case interviews were more of a discussion.
Confirmed questions6 questions
- Technical questions for Python were of average difficulty.
- Technical questions for SQL were of average difficulty.
- The first section of the final interview was consulting, which was quick and generic. It was hard to see how one could prepare for it beyond using STAR stories from their resume.

Technical Coding Case Presentation Behavioral
Visa's Data Scientist interviews generally start with a recruiter screening, then move to technical coding challenges using Python or SQL. You'll also be tested on your knowledge of machine learning fundamentals, statistics, and modeling. Be prepared for case studies related to fraud, risk, or personalization, as well as exploratory data analysis and metrics. The onsite portion involves panel interviews where they'll assess your communication skills, ability to collaborate with stakeholders, business sense, how you design experiments, and your skills in presenting insights. They'll also ask behavioral questions to gauge culture fit and your expectations.
