I've been transitioning from finance to tech, and coding interviews are definitely a challenge. I find myself getting stuck on algorithm questions. I’ve been doing LeetCode for a few weeks now but feel like I’m hitting a wall at times. Any advice on which types of problems are most commonly asked?

Also, I've heard mixed opinions on whether to focus on depth with fewer problems or breadth with many problems. Right now, I'm leaning toward breadth, but I'm not sure if that's the right approach. Any insights from those who've been through this would really help me figure out my next steps.
