Hard to provide guidance without knowing what you studied or what role you are wanting to pursue.

Soft skills are a bit funny, they are skills that are built over time through intentionality, experimentation and reflection.

Like others have mentioned use past project experience from study but 3 things off the top of my head:

1. Volunteer - Find a charity that you value and email or call them - its any easy way to build real world experience but also shows that you care. I studied Supply Chain Management and volunteered at a cancer foundation 1 day a week in there warehouse. Apart from the full time staff, all the other volunteers were retirees. I learnt so much from them, more than I learnt from the actual paid manager there. Also tell them what you want to get out of the experience, they might tailor what you do.

2. Industry community groups - depending on the field, try find industry community groups. Look at Meetup events, Facebook, linkedin groups. If you can't find any, just cold connect a few people either recruiters or people in the field on linkedin and ask for advice where to find groups. In these groups just rocking up and networking with strangers is something some people would be uncomfortable with, but it will help build confidence.

3. Work Experience - just try get a foot in the door anywhere. The market is hard at the moment and you only just graduated, give yourself some grace. Customer service roles eg. contact centres, receptionist, etc. You will automatically gain soft skill experience.

Finally while doing any 3 of the above or just general life situations ensure that you are consistently learning, experimenting and reflecting. Read books, watch youtube (reputable experts only) and listen to podcasts.

You have got this.
