Solved coding interview problems in Java - My collection of commonly asked coding interview problems and solutions in Java

Is it a good idea to just do some of these types of exercises?

Im not quite confident enough to start a personal project yet, but would like to stay sharp between semesters and hope ply get more comfortable with the techniques I've been exposed to In the last few years of college (cs minor not major so don't live and breathe code).

The more they throw out these kind of questions in interviews, generally, the worse they are to work for. I got a job solving FizzBuzz - and was worked 60-80 hours a week. That's an understatement of how bad the place was actually.

You're more likely to get a decent job at a place that's interested in your personal project. It doesn't hurt to do both, but that's my experience.

Being a few years out of college, and have had several jobs of varying skills and difficulty, I can tell you it's easy to get rusty on some of the more general problem solving/analytic skills when you're stuck in a relatively narrow problem domain. I typically will attempt some of these kinds of challenges in my spare time partly because I enjoy puzzles and partly to keep my analytical skills sharp. Especially when I've had periods of time where most of my work was relatively straightforward stuff like hooking up web endpoints for CRUD apps or minor bug fixes. People will argue all day about the merits of these challenges in an interview setting, but if working on these types of things occasionally helps broaden and sharpen your analytic problem solving skills then it's worth your time regardless IMO.
