I agree totally- not only does it keep you going, and gives some structure to your day, it also gives you the opportunity to demonstrate at interview the skills you've been developing/ fine-tuning ( e.g. team-work, time-management, leadership, initiative, planning, public-facing/ customer relations etc). And, to an employer, it demonstrates that you are giving of your time, and that you care about the community you are in- all positives for an employer. I think it also builds your confidence to be able to talk about yourself at interviews.
For
@mitchell1996 and
@l4toffee (and anyone else)- from an employer's perspective: I have recently had to trawl through 50+ applications for a job I'm helping interview for. In that process, having a really clear, easy-to-read CV is vital (if it's hard to read, it's going to put employers off), but the most important thing is a strong supporting letter that clearly shows what skills/ experience you have that will be directly useful in the job, and how. So, you don't necessarily have to have had like-for-like experience, but you have to be able to "sell" yourself, and to demonstrate how you will fill the specifics of the job description. It's always good to get someone else to look at this for you too, as typically we don't often talk ourselves up (especially if you're feeling depressed from being out of work for so long).
I hope that's of use, and please feel free to send me a message if you want to ask for any specific advice
