TL;DR
A programmer shares the four questions asked during a 1994 Microsoft internship interview, reflecting on their solutions then and how they might differ now. The story offers insight into early tech interview practices and their evolution.
A programmer has shared a detailed account of the four programming questions asked during his 1994 Microsoft internship interview, providing insights into early tech interview practices and their evolution.
The interview consisted of four questions: copying a rectangle between buffers, copying a string, implementing a flood fill detection, and a more complex graphics problem. The questions were asked by different interviewers on the same day, with increasing difficulty. The individual recalls the specific questions and his responses, noting that some questions seem simpler by today’s standards, while others remain interesting challenges.
Confirmed details include the exact nature of the questions, the context of the interview setup, and the interviewer’s instructions. The interview took place in 1994, likely in the early to mid-1990s, with the questions centered around basic graphics and string manipulation in C. The author’s recollections are based on personal memory, and some specifics, especially about the third question, are remembered as approximate.
Why It Matters
This story provides a window into the early days of technical interviews at major tech companies like Microsoft, illustrating how questions focused on fundamental programming skills related to graphics, memory, and data manipulation. It highlights how interview questions have evolved over nearly three decades, reflecting changes in technology and hiring practices. For readers, it offers perspective on how foundational programming concepts remain relevant, even as the complexity and style of questions have shifted.

Background
In the early 1990s, technical interviews at Microsoft and similar companies often involved on-the-spot coding questions designed to assess fundamental programming skills. The questions shared by the former intern include buffer manipulation, string copying, and graphics algorithms—core topics in systems programming and graphics development of that era. This period predates widespread internet resources and online coding platforms, meaning interviewees relied heavily on their understanding of low-level programming in C. Over time, interview formats have shifted towards behavioral assessments and algorithmic puzzles, but these questions reflect a different, more hands-on approach to evaluating technical competence.
“The questions were straightforward but required a solid understanding of pointers and memory manipulation, which was typical for the time.”
— Former Intern
“They wanted to see if I could write efficient, correct code on the spot, especially for graphics-related tasks.”

Key Questions
Are these questions still relevant for modern programming interviews?
While some core concepts like memory manipulation remain relevant, modern interviews tend to focus more on algorithms, data structures, and system design, often in a more abstracted or high-level manner.
Did these questions accurately reflect the skills needed for a Microsoft internship in 1994?
Yes, they focused on practical, low-level programming skills necessary for graphics and system programming, which were highly relevant at the time.
How have interview questions at Microsoft changed since 1994?
They have shifted from direct coding on the spot to include behavioral questions, algorithmic puzzles, and system design, reflecting changes in technology and hiring philosophies.
What can current programmers learn from these historical questions?
Fundamental programming skills, especially understanding memory, pointers, and data manipulation, remain valuable. Revisiting these questions can reinforce core concepts that underpin modern software development.
