Technical Behavioral
I applied through an agency and went through three rounds of eliminations. The first round was about Java, SQL, and DSA basics. The second round involved discussing my projects, where I had to explain the design choices I made, the difficulties I encountered, and how I solved them. I made sure to emphasize my problem-solving abilities, debugging skills, and how I managed to boost performance and make systems more reliable while developing.
