The application process began with an online form where I submitted my resume and a cover letter. After a few days, I received an email inviting me to the first round, which was a case study.

1. Analytical Quiz and Speaking skills

The selection process involved two distinct stages designed to assess a range of skills in the candidates.

The first stage comprised General Aptitude and Mathematics multiple-choice questions (MCQs). This section tested the candidates' quantitative abilities, logical reasoning, and overall intellectual capacity. The questions ranged from basic arithmetic and algebra to more complex problems involving geometry and data interpretation. This stage aimed to filter candidates based on their analytical and problem-solving skills, which are crucial for success in any business environment.

The second stage required candidates to submit a live video recording. Each candidate had to speak continuously for two minutes on the topic "Technology in Business." This video submission was a critical component of the selection process, as it assessed the candidates' communication skills, clarity of thought, and ability to articulate ideas coherently under pressure. There were no breaks allowed during the recording, adding an element of spontaneity and ensuring that the candidates could think on their feet.
