The interview: 30-minute case study with a Senior Data Scientist about Credit card profitability calculation, basic arithmetic. The math was straightforward, conversation was smooth, and the interviewer described additional interview rounds ahead. But an automated Workday rejection arrived minutes after the interview ended. I suspected the interview was a formality to satisfy a PERM (green card) process for an existing employee, not a genuine hiring effort.

The first stage went well - statistics, analytics, and modeling type of questions. I asked for prior information before the interview though on what it would entail. the interviewer was nice and gave room for questions and time to figure out answers and I thought it went well only to receive an email "thanking me for going through their stages" when I I did just one alone.
