I've heard all kinds of arguments for about how whiteboard coding interviews should be obsolete, and that they usually doesn't reflect how good you are as a developer. But I've been polishing my skills with data structures and algorithms for a few weeks (learning this stuff for the second time since years ago in college) and I get this feeling that I'm becoming a much better programmer by practicing these things. And having access to all these things in the "working memory" of my brain has made me now think of solutions I couldn't before. But then - it may be that right now I'm working on embedded systems so this efficiency matters much more, earlier while doing full stack web development I didn't care about these much except while playing with strings maybe. So it might be dependent on your niche. What do you guys think?
