How has it fared for you so far in the job market, have you started seeking yet / talking to recruiters or employers?

I'm not looking for the job, so hard to tell. Everything depends on your unique situation, but most likely the nanodegree alone will not be enough to get a senior technical position. The good experience with algorithms is still important. Some books which I usually suggest: "Gayle Laakmann McDowell - Cracking the Coding Interview - 2016" and "The Algorithm Design Manual Second Edition 2008".
