Selected
I appeared for an interview before Mar 2024.
The aptitude test mainly covered logical reasoning, quantitative aptitude, and basic programming concepts. Questions were of moderate difficulty, with some time-based problem-solving challenges. Practicing common aptitude topics like puzzles, numerical ability, and coding fundamentals can help in preparation.
The group discussion round focused on general topics related to technology, current affairs, and workplace scenarios. The evaluators were looking for clarity of thought, communication skills, and how well candidates could present their points while engaging with others. Staying confident and actively participating helped in getting selected.
