User data holds significant potential for gaining insights and guiding product development.

7. What key metrics would you track to measure success of the Fever app?

To assess Fever app performance, I would focus on metrics capturing engagement, retention and conversions such as:

• MAUs/DAUs to measure overall usage

• Churn/retention rates to quantify user loyalty

• Session length/frequency to gauge engagement

• Scroll depth to see content consumption

• Click-through rates on recommendations

• Conversion rates for transactions or sign-ups

• Ratings and reviews to capture user sentiment

• Surveys to directly measure satisfaction

Analyzing trends across these metrics can provide a holistic view of app success and point out areas for improvement. The key is choosing actionable metrics aligned to business goals.

8. How would you detect fraud on the Fever platform?

Here is a multi-pronged approach I would take to detect fraud on Fever:

• Analyze account patterns – unusually high activity could signal bots

• Monitor for duplicate accounts using emails or devices

• Check usage analytics for abnormalEngagement levels

• Employ clustering to uncover groups of frauAccounts

• Develop a supervised model using past labelled fraud data

• Continuously monitor and tune models to combat evolving fraud

Leveraging analytics coupled with ML provides a robust fraud detection framework while minimizing false positives for legitimate users.

9. What techniques could Fever use to build an effective recommender system?

Some best practices for building an effective recommender system include:

• Collaborative filtering to match users with similar preferences

• Content-based filtering using event attributes and metadata

• Hybrid approaches combining collaborative, content-based, and context-aware filtering

• Utilizing rankings or implicit feedback instead of explicit ratings

• Incorporating neighborhood and matrix factorization models

• Leveraging ensemble methods to reduce bias and variance

• Optimizing for accuracy, diversity, novelty, and serendipity

• Re-training models frequently with updated interaction data
