1. Your train/test event rate is 10% but oot test data event rate is 5%. Why did you build the model when with 1:10 event rate without checking the real time data for the next 6 months, which is 5%? - I have 14 years of exp including 8 years of consulting. This is the worst interview question I ever had. 2. This question was asked 3 times. You are building a prospect model to target clients for house refinances, at what stage are you building the model? Underwriting, funding? - It was a surprise to receive such questions in interview. I told them that we are identifying the prospects for marketing before even they reach out/start refinancing but they kept asking me the same questions. Looks like they just want to prove they know couple of things about mortgage industry but it was stupid. 3. I mentioned about a summarization project build on llama2 for my finance company built using call transcripts. Interviewer accused me of lying as he thinks I can't build model because ppl discuss ssn numbers and the details about other companies. Seriously? You are in a senior position and you don't know what's synthetic data or how customer data is redacted internally etc? 3. They are super rude from the start during the project review. I lost interest after 15 minutes as they are constants demeaning my current company and the projects we do when they don't even understand the basics of DS.
