I am really having a problem with my speaking skills especially one-on-one. Can you give me some advice or link about improving speaking skills coz I think it will really be hard to get hired. 
in my opinion the way to be a good speaker is:
Always set clear goals in our conversation, Always know who we are talking to, Understand our strengths and weaknesses, Be yourself and look natural, and Eye contact with people in front of us, with eye contact as if we managed to bring them in. into what we're talking about and get them to focus on what we're talking about.
