Coding problems asked in my Data Engineering Interview
List of coding questions that I was asked to solve in my data engineering interviews of different companies
For the last 4 months, I interviewed with multiple companies from MNCs to startups. Big or small, all of them were product-based companies.
ShareChat, Uber, and Quillbot were offering WFH, whereas Booking and Agoda were onsite opportunities in Thailand and Amsterdam respectively. There are a few more companies that I interviewed with but they didn’t ask any coding questions. What I have realized is that big product-based companies focus on coding and problem solving along with Data Engineering concepts whereas startups mostly focus on understanding your Data Engineering knowledge.
In this blog, I have listed all the coding questions that I have been asked in the companies I have interviewed with.
