The questions in written test varied in difficulty, mostly falling within the easy to moderate range. In the technical interview, I elaborated on the Python project I had worked on, discussing the implementation of neural networks and recurrent neural networks (RNNs) for various tasks. I explained the concepts of forward and backward propagation in neural networks and how RNNs can be used for sequential data analysis. When asked about SQL concepts, I provided explanations for INNER JOIN, OUTER JOIN, LEFT JOIN, RIGHT JOIN, as well as ORDER BY and GROUP BY clauses. I also explained the difference between sorting in ascending and descending order in SQL. For the puzzles, I solved Puzzle 1, the Socks Puzzle, by explaining the probability-based solution to the interviewer. For Puzzle 2, the 3 Bulbs and 3 Switches Puzzle, I discussed the approach of toggling switches and identifying the corresponding bulbs that light up. In the HR round, I shared my experience during the recruitment process and highlighted my skills in both computer science and electrical engineering. I explained my expectations from the job role and expressed my willingness to contribute effectively. I also asked questions about the company's expectations from newcomers in the analyst field. Overall, the interview process falls under easy category. The written test evaluated basic language, analytical, and quantitative skills . The technical interview focused on assessing technical knowledge and problem-solving skills, while the HR round mainly evaluated confidence, communication abilities, and alignment with the job profile.
