So the interview was made of a written test and then 2 interview sessions. The written part had 4 sections: Aptitude, English, MCQs on SQL, OS, and Machine Learning. Then Round 2 was all about problem-solving, focusing on topics like 2D matrix, linked lists, permutation combinations, and tree traversals – basically, data structures and algorithms. Finally, Round 3 was an HR round where I had to introduce myself, talk about my projects, and answer questions like why I want to join the company, plus some other basic HR stuff.

So for the technical role, there were 2 rounds. First, an online test with sections on aptitude, verbal and logical reasoning, MCQs on SQL, Java, and HTML, and also MCQs on machine learning. Based on your test performance, your role is determined. If you're selected for the BA role, there's a group discussion (GD), but for the technical role, it's a direct technical interview. The technical interview covers your projects, SQL queries (specifically joins), and Java concepts. If you do well in the tech round, you proceed to the HR interview. I learned SQL and Java from javatpoint.

The process started with two technical rounds focusing on AWS and Terraform. After that, there was an HR round for salary negotiation. Rounds 4 and 5 were fitment rounds, which felt similar to technical ones. It was a poor experience overall because the process was complex, and the fitment rounds after HR seemed shady, making me feel like they weren't serious about hiring.
