Computing the Median: A Favorite Software Engineering Interview Question

The post introduces a classic interview problem that asks candidates to find the median of a data set. It explains why the median is a useful statistic for assessing algorithmic skill. Several solution approaches are compared, from sorting the list to using selection algorithms. The author highlights the trade‑offs between time complexity and code simplicity. An example implementation in a common programming language is provided. The article discusses how the problem can be extended to streaming data. It also notes common pitfalls interviewers watch for, such as off‑by‑one errors. Readers are encouraged to practice the problem to improve their interview readiness.
