This article provides an in-depth analysis of the TSMC interview process, shares sample questions, and offers practical preparation tips to help you ace your interviews. offers practical preparation tips to help you ace your interviews.
TSMC Interview Round 1: Coding
The first round of TSMC's software engineering interviews typically focuses on algorithmic coding and programming. Questions are questions are designed around real-world semiconductor scenarios, emphasizing candidates' programming proficiency, logical thinking, and questions are designed around real-world semiconductor scenarios, emphasizing candidates' programming proficiency, logical thinking, and understanding of hardware-related contexts. Unlike LeetCode problems, these questions prioritize code correctness, modular design, and practical application in semiconductor manufacturing processes such as wafer test data processing or production scheduling optimization.
Sample Coding Questions
Description: Given an array representing a stream of semiconductor wafer test results (where 1 indicates pass and 0 indicates fail), write a function to calculate the maximum number of passing results within any sliding window of size k.
Input: tests = [1, 0, 1, 1, 1, 0, 1, 1, 1, 0], k = 3
Output: 3
Explanation: The window [1, 1, 1] contains three consecutive passing results, which is the maximum count.
TSMC Interview Round 2: System Debugging
The debugging round is a distinctive feature of TSMC interviews, evaluating candidates' ability to troubleshoot complex systems. Candidates are typically provided with a simulated wafer test script or production scheduling code (written in languages like Verilog, Python, or C++) and must identify and fix issues. Candidates are typically provided with a simulated wafer test script or production scheduling code (written in languages like Verilog, Python, or C++) and must identify and fix issues.
Sample Debugging Task
Problem: Given a Python script for calculating wafer test yield rates, identify and fix errors causing incorrect results for certain inputs.
Code Snippet (with bug):
def calculate_yield(tests): total = 0
total = 0
passed = 0
for test in tests: total += 1
total += 1
if test == 1: passed += 1
return passed / total # Bug: no handling for total = 0.
return passed / total # Bug: no handling for total = 0TSMC Interview Round 3: System Design
The system design round assesses candidates' ability to architect solutions tailored to semiconductor manufacturing. include wafer production scheduling systems, wafer testing pipeline designs, or data analytics platforms. Unlike tech companies, TSMC' s system design questions emphasize hardware constraints (e.g., power consumption, latency) and operational efficiency. s system design questions emphasize hardware constraints (e.g., power consumption, latency) and operational efficiency.
Sample Question
Task: Design a wafer testing scheduling system capable of managing multiple testing machines and wafer batches with varying priorities. Consider factors such as machine utilization, test time optimization, and error handling.
