How does one bring in the confidence to apply for a job position without having the right skills. There many cases where employees take up a job which is totally irrelevant from the previous and still strive.

How do you push through your worst times?

Hi, I have a background in offshore engineering and engineering management. I am thinking to pursue job opportunities in strategy and management consulting using data analytics/ data science. Do I need internship in consulting or analytic firm prior to these applications ?
