I never said it was a problem. I have a CS degree so it doesn't hugely bother me. IMO, it's a necessary hurdle to ensure that you aren't swamped by thousands of candidates at every location.

With that being said, I would consider knowledge of DSA and the knowledge required for a FAANG level interview to be subtly different. There's a big difference in knowing how to implement basic data structures, sorting algorithms, and implementing BFS/DFS on a graph, and being able to dissect a LeetCode style coding problem and implement a solution that's good enough for a FAANG-tier company.

As far as people being one-trick ponies, I would disagree. They've simply specialised in a different aspect of software engineering, and just like how a Google engineer can learn to build a dynamic API wrapper with Ruby meta-programming and Rails, a Ruby engineer can learn dynamic programming and Dijkstra's algorithm.
