Been grinding LeetCode but still struggling? Check out this PayPal interview question!
If you still think that acing a PayPal interview is just about solving LeetCode problems, you might be in for a surprise. Recently, PayPal's technical interview style has been shifting, focusing more on system design thinking and real-world engineering problems, rather than just algorithmic brute force solutions.
Take this PayPal Multiprocessor Scheduling interview question as an example. It not only tests basic greedy algorithms but also involves real-world considerations such as processor performance degradation and task scheduling optimization. These types of problems are difficult to match with standard LeetCode questions, as interviewers are more interested in assessing your problem-solving approach and optimization strategies.
Problem Statement: Multiprocessor Scheduling
Description:
Multiprocessor systems use multiple CPUs to perform various tasks. This increases throughput and reduces response time. In this problem, a multiprocessor system has a certain number of processors. Each processor has the ability to schedule a limited number of processes in one second. However, after this scheduling, the processor's ability is reduced to floor(ability/2). Given the processor’s abilities and the number of processes, what is the minimum time required to schedule all the processes in the system?
Example:
n = 5 # number of processors
ability = [3, 1, 7, 2, 4] # initial processing capacities
processes = 15 # total number of processes
Is Your LeetCode Still Enough? How to Adapt to These Interview Changes?
Compared to classic LeetCode greedy algorithm problems, this question has several key differences:
✅ Involves real-world system scheduling, not just pure algorithmic logic ✅ Processor performance degradation adds dynamic complexity to the greedy approach ✅ Evaluates candidates’ resource management and optimization thinking
This means that you can't just rely on standard LeetCode solutions—you need to think deeper:
1️⃣ Can you quickly identify the optimal strategy? 2️⃣ Have you considered real-world constraints like performance degradation? 3️⃣ Is your solution scalable and efficient for large-scale data?
At companies like PayPal, interviewers focus more on problem decomposition skills, dynamic decision-making, and optimization strategies. If you're still relying solely on memorizing LeetCode solutions, you might be “grinding 300 questions but still failing to land an offer.”
