I have been working as a big data analyst for the past few years. I was keen for career growth and realised that getting certified as a big data analyst by a reputed organisation is the key to my career growth. As a full time working professional, I required online certification on big data analytics to test my knowledge and gain credibility. After intensive research for the best certifications available online on big data analytics, I zeroed down to Global Tech Council’s Certified Big Data Expert Certification. After getting certified, I got the growth I was looking for in my career. I would recommend this certification to all the working professionals aiming to get career growth in the big data domain.
