Your knowledge and your skills are not only what you learnt at school or your previous job, but it is the mix all the experiences you've had. Therefore be curious on the world around you, and catch what helps you to grow and develop as real person. Be honest and show how you really are, and prompt and flexible adapting to the situation, but also staying tuned on your values.

Network. Everyone talks about networking, but it truly is a life hack. After University grades are gone, you'll still be reviewed once a year or so, but the amount of written feedback is much more limited. Building a strong network is now your new good grades and it will strongly dictate your future career opportunities. Also remember that networking is not only for those in positions above you, so be nice to everyone. Buy in. Buy in to the culture, to the social and to the company. Show an interest and ask questions. This will make your worklife become more enjoyable and also help you with your networking, especially with those in positions above you as they are more bound to company values and culture.

Main assets for a company are people - Be reliable, as a company is a sum of individuals. Others much be able to rely on you, your words and your actions.
