Am I Ready?

Hi all, Just wanted some advice. I have a CS degree, did some google interviews in college and a year after first job, but failed -mostly due to nerves and not doing mock interviews. I love DS & Algos, and passionate about the code. I coded for my main job for 2-3 years in C, familiar with Python to write a TWO-SUM solution, but now, I haven't coded in 2 years because I moved to a leadership role.... Nevertheless, I have a technical assessment coming up because of my embedded background. I enjoy coding and learning to code. I am confident I can pick up python again for interview and can solve the TWO-SUM or Parenthesis problem again within 30 minutes,.... TL:DR How long should I request to prep for a technical interview (solve medium lvl questions well) if I am familiar, but not implemented, with DS & Algo (lists, hashmaps, binary sort, trees, A*, Dijaskta, BFS, & DFS)? Thanks. I am ready to study hard 3 hours a day if i have to, and honestly, it sounds like a fun time to catchup what I've been missing. I believe this is an early career or mid career role...
