bp Software Engineer interview questions

I had an interview that included several components. First, I tackled two Data Structures and Algorithms (DSA) questions: one from Arrays that could be solved using a HashMap and another one from Graphs. The Graph question proved to be quite challenging. I wasn’t required to write the entire code, but I needed to explain the overall flow of the code. After that, I provided pseudocode and discussed any necessary optimizations. Next, they asked me questions on various computer science fundamental topics, including Computer Networks (CN), Object-Oriented Programming (OOP), Database Management Systems (DBMS), and Operating Systems (OS). In my case, they focused heavily on DBMS since it was highly mentioned in my resume. I was asked questions about normalization, including the First Normal Form (1NF), Second Normal Form (2NF), denormalization, and other related topics. Following that, we moved into the project and internship section, where they inquired about my real-world, industry-relevant experience. They asked detailed questions about my projects, including whether my project had been deployed, and they verified its deployment. After all these discussions, they scheduled my HR round immediately, where I answered typical HR questions, particularly regarding why I wanted to join BP. The interview feedback was positive, and I was informed that my chances of moving forward were high. However, after two weeks, I was not shortlisted because they preferred candidates with a Computer Science background.
