Description For System Signal Integrity Engineer

Join Apple's Mac organization as a System Signal Integrity Engineer where you'll be at the forefront of hardware innovation. This role focuses on system-level signal integrity design, analysis, and validation for Mac and Accessory products development, from conception to production. You'll work with cutting-edge technology, applying your expertise in high-speed SerDes, parallel bus, and single-ended signaling.

The position offers an opportunity to work with state-of-the-art tools and technologies, including 2.5D tools (PowerSI, SIWave, Sentinel-PI, nSys), 3D Full wave (HFSS, nWave), and quasi-static tools (Q3D, nApex). You'll be involved in designing custom connectors, cables, and supporting factory builds while ensuring electrical compliance.

As a key member of the hardware team, you'll leverage your knowledge of various industry SerDes standards (USB, DisplayPort, HDMI, MIPI, etc.) and parallel bus interfaces. The role requires expertise in measurement techniques using frequency and time domain tools, along with programming skills in Matlab/Python/PERL.

This is an excellent opportunity for an experienced professional to make a significant impact on Apple's flagship Mac products, working in a collaborative environment that values innovation and technical excellence. The role combines hands-on technical work with strategic thinking, requiring both deep technical knowledge and strong communication skills.

Explain dynamic programming using the knapsack problem, including subproblems, recurrence, base cases, and complexities.

Data Structures & AlgorithmsMedium

Let's explore dynamic programming with a classic problem: the knapsack problem. Imagine you have a knapsack with a limited weight capacity, and a collection of items, each with its own weight and value. Your goal is to select the items to put into the knapsack to maximize the total value, without exceeding the weight capacity. Specifically: Problem Statement: You are given a knapsack with a maximum weight capacity W. You are also given n items. Each item i has a weight wi and a value vi. Determine the maximum total value of items that can be placed in the knapsack without exceeding its weight capacity. Example: Knapsack capacity W = 10 Items: Item 1: weight = 6, value = 30 Item 2: weight = 3, value = 14 Item 3: weight = 4, value = 16 Item 4: weight = 2, value = 9 What is the maximum value you can obtain by putting items into the knapsack, and which items should you choose? Explain how you would approach this problem using dynamic programming. Be sure to define the subproblems, the recurrence relation, and the base cases. Also, discuss the time and space complexity of your dynamic programming solution.

How do you debug a lagging, mission-critical server using only a terminal?

System DesignMedium

You're troubleshooting a mission-critical server (cannot be rebooted) that is experiencing severe lag. You only have terminal access. Describe your debugging process, including specific commands and tools you'd use to diagnose the issue. For example, would you start by checking CPU usage, memory consumption, or disk I/O? What commands would you use to identify the most resource-intensive processes? How would you investigate potential network bottlenecks or file system issues? Be as detailed as possible in outlining your approach to pinpointing the cause of the lag and suggesting potential solutions, keeping in mind that a reboot is not an option.
