Is the difficulty level of coding questions asked during Google interviews same irrespective of the candidate's YOE/target level or does it scale with experience/target levels ? Asking about DS/Algo questions, not system design questions.
It's kind of at the discretion of the interviewer. Some of my questions, I can ask everyone, but my expectations will differ between a new grad and a seasoned pro.
Could you give an example of what you would expect from a candidate with 2 yoe as opposed to a candidate with 5+ yoe ? For any one standard LC problem, not asking for your signature interview question :-)
I think in these questions, maturity manifests in the form of a higher quality thought process, meaning things like better clarifying questions early on, and thinking more moves ahead, which leads to better execution and better factored code. In other words, from a new grad (< 1 YoE), I expect more cowboy algorithmic hackery. From someone more experienced, I expect... Engineering.
Wild guess, but judging by Google's ability to select the best of the best, I presume they aim to ensure you are capable of applying a language in challenging space rather than solving every arbitrary programming question leetcode has to offer.
Not really... Most of the questions are the same, and expectations vary depending on the target level for a particular interview.
