There are a handful of skills that go a long way regardless of what career path you choose. In my experience, you should really try and develop and hone in on the following:
- Good public speaking and the ability to converse on a broad range of topical issues. I recommend reading global news (not just US news) daily to get a better understanding of the world and it provides for great conversation if you ever have to talk to a recruiter, manager, executive etc.
- Volunteer and give back to the community. Companies like to see people who are selfless and care more about their peers and the environment than just themselves! A really easy way to demonstrate this is to volunteer or get involved in your local community.
- Have a number of extra curricular interests. This is a HUGE point. Companies don't want people who've just studied their whole lives. They want people who are well rounded and have a variety of interests, be it sports, art, climbing, hiking etc. Make sure you're well rounded.
Hope this helps!
