My interviewer was very chill. We started with a standard behavioral question, and he asked a couple of follow-ups.

For the technical portion, the first question I got was "Valid Parentheses." The second, follow-up question was how I would implement the stack I used in the last question using two queues (reverse of the Leetcode question "Implement Queue using Stacks"). I did not need to actually write any code for the solutions; the interviewer was satisfied with my verbal responses.

Valid Parentheses

Implement Stack using Queues
