I applied through college or university. I interviewed at o9 Solutions (Bengaluru) in Jan 2026
Interview
The interview process consisted of three stages:
Online Assessment – This included aptitude questions and SQL-based questions. The SQL section focused on fundamental concepts like SELECT queries, filtering, sorting, and basic JOIN operations.
Technical Round 1 – The interviewer discussed my academic and personal projects in detail. They asked me to explain the architecture, database design, and how data flows through the application. SQL questions were also asked, and I was required to write and explain queries.
Technical Round 2 – This round included more SQL problem-solving, including a JOIN-based scenario question. I was also given one logical/coding question. Apart from technical topics, the interviewer asked some normal questions to understand my mindset, learning attitude, and career goals.

Question 1
One of the key questions was a JOIN-based SQL scenario where I had to retrieve specific data from two related tables using the correct join condition.
It was good. Asked questions related to extra curricular activities, case study and basics of SQL.
They mostly check your problem solving skills and basics of SQL.
If you have knowledge of supply chain it will be an edge for you.
