Waiting for result
I had an interview with Paypal recently, which started with a recruiter call. The recruiter was quite friendly and explained the role in detail. After this, I had a technical phone screen that included questions related to data analysis and machine learning. One of the most challenging questions was about a real-time fraud detection scenario, where I had to design an algorithm based on certain parameters. Overall, I feel the interview went well, but I’m still waiting to hear back.
