1,000,000% this. If a senior engineer can’t explain it to you in a way you understand - even if you are a lot less experienced - that’s THEIR deficiency. Not yours. When this happens, it means THEY actually don’t understand it well enough.https://twitter.com/noahsussman/status/1170870234066165760 …
Love this. Only caveat is that the junior has to be coming from a place of curiosity. I've run into tons of people (not just Devs) who are more interested in being right, than in learning.
