I did a bug squash interview when I was interviewing for new grad positions and it was one of my favorite interviews (both as an interviewee and an interviewer)

- People were allowed to use their favorite IDEs - so you could see how proficient some people were

- Great engineers are really really good at debugging - it was great to see how people debugged and it helped me pick up a few things as well

- People couldn't leetcode their way out of this
