Quality Engineer Interview Experience - San Jose, California
Process
I had a technical phone screen. I provided a solution with O(1) runtime and O(n) space. The interviewer was fixated on optimizing the solution to achieve O(1) space.
Looking at the solution online, I doubt if someone interviewing for a QE role would be able to answer it without already knowing the solution.
In my professional experience of over 8 years, I have never come across such complex problems at work as a QE. If Confluent QEs are solving such problems in their day-to-day, kudos!
Questions
Design a stack that supports getMin() in O(1) time and O(1) extra space.
