I'm trying to use my study time wisely and can't decide whether to focus on building software projects or practicing coding challenges. I already understand data structures, algorithms, and several other programming fundamentals. Which option would help me more with getting hired and becoming a better developer, and how should I balance the two?

Think of coding challenges as training exercises and projects as actual games. Professional developers still practice fundamentals, but they also need to apply them in realistic situations. A reasonable plan would be to spend most of your time on one substantial project while doing a smaller, consistent amount of coding practice—then increase the challenge practice when you’re actively applying for jobs.
Projects are the better choice if your main goal is becoming capable of building software. You can deliberately use data structures and algorithms in them instead of practicing those topics in isolation. Build something moderately complex, encounter real problems, fix them, and document what you learned. That experience is much closer to day-to-day development than solving a stream of short puzzles.
Do both, but give them different purposes. Use coding challenges as focused practice for algorithms and interview preparation. Use projects to learn the parts that challenges usually don’t cover: design, debugging, testing, user requirements, deployment, and working with unfamiliar libraries. A project also gives you something concrete to discuss in interviews, even if it isn’t the only reason someone hires you.
If your immediate goal is passing interviews, coding problems may deserve more time because many companies include them in their screening process. However, the exact amount varies by region, company, and job type. Don’t spend all your time memorizing patterns—make sure you can explain your reasoning and write clear code.
It really depends on the companies and roles you’re targeting. Some employers use coding challenges heavily during online assessments and interviews, while others care much more about your previous work, practical projects, and how you approach unfamiliar problems. Coding practice can help you pass certain interview stages, but it isn’t a substitute for learning how to build and maintain real software.
That matches my experience too. I’ve seen coding questions show up in some hiring processes, but other interviews focused on past projects, system design, and explaining technical decisions.
And practical experience still matters. A coding challenge might get you through an assessment, but you’ll need to discuss real decisions and past work in later interview stages.
