Bajaj Finance Data Engineer interviews, decoded.

It was a completely online 3 phase interview. Mostly data science and aiml questions were asked. No HR interview. One aptitude round, one technical MCQ round, and one technical interview. The interviewer was patient and did not rush.

Had an aptitude test for 60 mins with 45 questions, followed by a technical interview. They asked some DSA questions, SQL queries, about projects and technologies I've worked on. The SQL queries were medium to difficult. They also asked about cloud technologies and analytical questions.

It started with an aptitude and coding test covering basic Data Structures and Algorithms. Then, a technical interview was set up, which went into SQL stuff like DDL, DML, and window operations. We also talked about PySpark, including how to make and use User Defined Functions (UDFs) with examples. There were also Machine Learning questions, asking to describe and implement ML on a given scenario. The interviewers were helpful, so if you got stuck, they'd guide you, encouraging you to ask questions and show how you'd figure things out, which is what they care about for real jobs.
