I guess maybe I&#x27;ve just been lucky (or perhaps have chosen which companies to talk to well) in that I&#x27;ve always had discussions closer to your &quot;what are the pros&#x2F;cons if you design an API to expose txns&quot; example than &quot;implement a red&#x2F;black tree off the top of your head.&quot; Perhaps this is coloring my judgement.<p>Honestly if someone asked me to code a red&#x2F;black tree, I&#x27;d probably say &quot;I remember that term, but I don&#x27;t for the life of me remember what it is exactly. If you want to give me part of the answer I can probably logic out the details on my own but I&#x27;m not going to do well on your memorization test.&quot;
