About

Prakhar has around 8 years of experience working as a data analyst across e-commerce, edtech, fintech, logistics, and B2B SaaS environments. His work has consistently been at the intersection of product and marketing analytics — using data to answer questions about where users drop off, which channels actually drive retention, and how to run experiments that produce reliable results rather than noise.

He started Data Analyst Interview after spending time helping friends and colleagues prepare for data analyst roles. The material he put together for that — SQL question banks, case study frameworks, Python exercises — turned out to be more useful than most of what was publicly available, so it became a website.

He has an engineering background from Shri G S Institute of Technology & Science and holds advanced certifications in SQL and Google Analytics. He has received the Excellence Monthly Award during his career in analytics.
