I was asked about model complexity and its impact on bias and variance, and also about gradient vanishing. The coding question was similar to LeetCode 815, but with pins and boards instead of other elements.

The coding question was not a standard LeetCode problem. I was asked to implement a system to determine if an IP address is on a blocked list, discuss the complexity, and improve the solution. I felt I answered well, addressing implementation, optimization, an...
## Preparation Tips & Key Takeaways ### What I Learned - It's crucial to manage the interviewer's expectations and guide the conversation to cover all necessary aspects, even if they interrupt frequently. - Even if I know a solution, clearly communicating the...
The coding question I received was to implement an expiring key-value cache. **My Approach:** 1. I started with a lazy deletion implementation. 2. Then, we discussed how to prevent out-of-memory (OOM) errors. 3. I was asked to create a separate thread to remov...
## Preparation Tips & Key Takeaways ### What I Learned - String parsing in coding interviews can be time-consuming; practice efficient parsing techniques. - For system design, understand the nuances of different components and their interactions, especially wh...
The coding round was a variation on a common algorithm problem. The problem-solving round focused on how I communicated with the interviewer and how well I could explain my thought process to find a viable solution. The problem was: Netflix home page viewport...
The coding question I received was: Design a framework that can execute tasks with dependencies. This included: - Defining a `Task` interface. - Designing the framework to handle dependencies between tasks. **My Approach:** 1. I began by defining the `Task` in...
The coding question I got was: LeetCode 2622. Cache With Time Limit Follow up: How would you clean up expired data? **My approach:** 1. First, I implemented the basic cache functionality using a dictionary to store the key-value pairs and their expiration time...
The coding question involved implementing a sliding window algorithm. The interviewer interrupted me at every line. I struggled, but I finished writing and testing the code. For the second question, I implemented deduplication logic for the Netflix home page....
The coding question I got was: ```python # We're analyzing user engagement patterns across different content. # # A user's engagement with a piece of content is defined by: # - "Abandoned" if they watched less than 25% of the content # - "Sampled" if they watc...
