The recruitment process you underwent consisted of four rounds. The first round was an online assessment. The second round was a communication assessment. The third round was a case study. The fourth and final round was an interview. In the online assessment, you were likely tested on your technical knowledge, problem-solving skills, and other relevant abilities. The communication assessment probably evaluated your communication skills, including your ability to articulate your thoughts clearly and concisely. In the case study, you were likely presented with a real-world scenario and asked to analyze it, identify the key issues, and propose solutions. Finally, in the interview, you were probably asked questions about your experience, skills, and qualifications. I hope this helps clarify the recruitment process you went through.
