Like the title basically suggests I'm asking for things an engineering student should do as an undergraduate.

Things that could give a competitive edge in the brutal Nigerian job market , post graduate scholarship application applications and so on. what do employers usually look for in candidate.
Are there any clubs , organizations(like IEEE) , certifications , projects or specific networks that could make me a better candidate. The only organization in my school is the IEEE, my school rarely hosts any tech events .Are there other organizations that would be important to an undergraduate , would it be useful to attend conferences and so on

Lastly , are there things you wish you did as an engineering student that would have made you a a better candidate overall.
