To become a data analyst in the competitive environment of the present day, one needs to have both technical skills, business and the skill of selling the story using numbers. With the increasing organisational shift towards data-driven decision-making, the interview process has changed to not only test your ability to write code, but also your ability to solve real-world problems as well. The key to success is to show that you are not just a technician; you are a strategic partner who can turn complex datasets into actionable insights that will bring in revenue and operational efficiency.
