Behavioral Technical
The first stage involved a meeting with two individuals. It began with an introduction to the project, followed by general introductions. Then, we delved into my background. Both interviewers appeared quite disinterested and unapproachable, possibly due to a perceived lack of connection. The questions they asked felt somewhat forced, and they didn't show much interest in my responses. While it started as a discussion, it became quite uncomfortable as the interviewers didn't seem fully engaged. It felt like they were going through the motions for diversity and inclusion purposes. Towards the end, they had to rush off to another meeting. They mentioned a second stage, but the interview didn't progress that far. The interviewers gave off a somewhat racist vibe.

Behavioral Technical Presentation
The interview started with a recruiter call, followed by a meeting with the Director. The final round consisted of 6 parts: 5 individual interviews and a panel interview. The process felt like they were trying to extract ideas. During the presentation, they focused on getting important info about my current work. Some interviewers were rude, and surprisingly, some lacked basic knowledge of data science concepts like prompt engineering and couldn't grasp business objectives or evaluation metrics without repeated explanations.
Confirmed questions5 questions
- Given a train/test event rate of 10% and an out-of-time test data event rate of 5%, why did you proceed with model building without verifying the real-time data for the subsequent six months, which showed a 5% event rate?
- Regarding building a prospect model for targeting clients for house refinances, at which phase would you develop this model: during underwriting or funding?
- I discussed building a summarization project with Llama2 for a finance company using call transcripts. How is this feasible given that individuals might discuss SSNs and sensitive company information?
