Design a Job Scheduler

Design a distributed job scheduler that can handle high-throughput job processing (10,000+ jobs per second), support both scheduled (cron-based) and ad-hoc job execution, include retry mechanisms for failed jobs, and maintain execution history for up to one year.

Leetcode 146. LRU Cache

Implement an LRUCache that supports O(1) average-time get(key) returning the value or -1 and put(key, value) which inserts or updates a key and, if capacity is exceeded, evicts the least-recently-used key. The core challenge is maintaining key-value storage together with recency ordering to enable constant-time access, updates, and eviction.

Job Scheduling Algorithms Implementation

Implement job scheduling algorithms including both First Come First Serve (FCFS) and priority-based approaches. The solution should handle job submissions with start times, end times, and priorities, and output the execution schedule with appropriate timing details.

Implement CRUD REST APIs

Design and implement basic CRUD (Create, Read, Update, Delete) operations for a REST API system. Include appropriate HTTP methods, request/response handling, and data management functionality.

Leetcode 528. Random Pick with Weight

Given an array of positive weights, implement pickIndex() to return index i with probability w[i]/sum(w); the typical approach preprocessing prefix sums and using a random number plus binary search maps the random draw to the weighted bucket in O(log n) time after O(n) setup.

Design a Scheduler System

Design a system that allows users to schedule events and processes them at specified times. Focus on the event staging architecture, including how events are queued, stored, and transitioned from scheduled state to active processing.

Design a Unique Identifier System for Customers

Design a distributed system that generates unique customer IDs for Netflix users during global signup, ensuring scalability and uniqueness across multiple data centers similar to Snowflake ID generation.

Tell me about a time you had to define the scope of an ambiguous project.

Leetcode 8. String to Integer (atoi)

Parse a string into a 32-bit signed integer by skipping leading whitespace, reading an optional '+'/'-' sign and the following contiguous digits (stopping at the first non-digit), and returning 0 if no digits are read; clamp the result to the 32-bit range [-2^31, 2^31−1] on overflow.
