If I'm interviewing with a dozen companies, it would take far less of my time, to do the initial phone screens with all of them. A typical HackerRank/Leetcode-style pre-onsite phone/online interview typically only takes 45 minutes to 1 hour. If I had to spend 5 hours on average implementing a custom project for a dozen companies, that would take me 60 hours in total. Even with the time spent studying, short 1-hour algorithm problem interviews take up less time. [1] Not to mention: I don't think time spent practicing problems on Leetcode/HackerRank is a complete waste. Sure, you're not going encounter hard algorithm problem everyday at work. But it builds certain skills that might be valuable eventually, as a developer.
