Case study: word ladder - find all paths

Sept. 17, 2019

Introduction


It is my 10:00 PM mock interview. I like to explore the algorithm and learn from all kinds of mistakes related to the algorithm.

Case study


Here is the transcript.

Actionable Items


I am very experienced to help interviewee to reduce anxiety. Usually at the very beginning, I will say that "I will ask you a graph algorithm. If you need hint, please let me know. Otherwise, we can move to an easy one, tree algorithm.". 

Also I need to find ideas to encourage the discussion, cover basic needs in terms of implementation, like path variable need to design remove action besides insertion. 

I should have spent 10 more minutes to break  the ice after the coding session, encourage the exchange of ideas, how to learn and work on algorithm problem solving in general.
