I applied through an employee referral. I interviewed at Visa Inc. (Atlanta, GA) in Aug 2023
Interview
The process was very long: -1 phone screen with the recruiter to go over my experience -1 technical video call: there was 1 Python coding question (basic pandas, group by, etc..) and 1 SQL coding question - panel interview with 4 different senior managers (data science & consulting ); 3 case studies and 1 technical question (statistics) Overall the only person who seemed to care about the applicant was the recruiter. I barely had a chance to ask questions about the role and when I did the senior interview (panel) could not even provide a clear answer. I was discouraged and did not to pursue further
