Rishabh N. - "I first asked few clarifying questions like the return array may need not contain the list of building in the same order, to which the interviewer agreed.

There's no right answer: interviewers want to understand how you think and how well you can explain your reasoning, rather than what you already know. Recall the formula for Fermi problems: Ask clarifying questions Catalog what you know Make equation(s) Think about edge cases to add to equation **Breakdown components of your"See full answer

Henry H. - "Overall, a successful Netflix viewing session requires that the user was able to find a piece of content that they loved watching. Now, to break this down, how we might define this: -Time browsing (from app open to content played) -Satisfaction --> inferred satisfaction: did user complete watching the piece of content? --> explicit: did the user rank that they loved the content (2 thumbs up)?
