I was able to land a couple of solid offers but you have to be really persistent. I kept chugging away a hour or so a day and 3+ on weekdays when kids slept in and basically made algos my thing apart from work and family (which worked out for me since I was able to come up with the Aho-corasick algorithm for a question I was asked). After a while I started enjoying the prep process since I was learning quite a bit too.
