Level: Mid-Level
Round: Phone Screen · Type: Coding · Difficulty: 3/10 · Duration: 60 min · Interviewer: Unfriendly
Topics: Load Balancing, Probability, Randomization
Location: San Francisco Bay Area
Interview date: 2026-01-15
I had a technical phone screen. I was asked behavioral questions and a coding question related to load balancing.
The interview started with a behavioral question: introduce myself and describe a high-quality project I worked on.
For the coding question, I was asked to write a function that randomly selects an IP address from a list of IP addresses for a load balancer, ensuring each IP has the same probability of being selected. The follow-up question involved implementing a weighted probability where IPs with higher weights have a greater chance of being selected.
