Welcome to your interview.
The question is on your right: Handle Missing Data in Hiring Models. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are building a model for a staffing platform to predict whether a candidate will be successfully placed in a role based on application, resume, screening, and recruiter activity data. Some fields are incomplete because candidates skip profile sections, recruiters enter notes inconsistently, and certain assessments are only available for part of the population.
How would you handle missing values in this dataset while training a production model, and how would your approach change depending on why the data is missing and which algorithm you choose?
