How would I negotiate a higher pay from a company that I've been working for a long time?

Hi! My name is Victor. I am a very dynamic person and my background is in Accounting & Finance. I am passionate about digital marketing and social media marketing. I am currently in recruitment. Do you think I should pursue my passion of joining a firm that embodies digitization or go with the safe route of being in the Financial Services industry? I am on a crossroad. Would appreciate your advise as I feel strongly that I would be a good fit in firms like Google, Maxis, Digi or Axiata where the environment is dynamic and we are constantly challenged to learn and grow.

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 ?
