Mostly behavioral with past experiences. Not much technical questions, but I heard this can depend on who interviews you. 2 45-minute interviews back-to-back. Heard back with decision within 2 weeks.
Technical questions and a take home project. Tech questions are related to statistics and math, not very hard but time-series specifically. Also, there are questions related to probability calculation. The vibe is casual and the interviewers are very nice.

Question 1
What is GATCH model.
How to tell if a time series is stationary or not.
Scheduled Superday with 2x 40 minute interviews back-to-back with different BofA employees (up to at least VP, Director+). Almost entirely behavioral, with just a few questions on languages and data structures you have worked with. Mostly about data communication. Super friendly and reasonable.
