Upon arrival, there were approximately 100 candidates. They were asked to register themselves on a laptop by entering their experience, CTC, and other details. This process took around 4 hours, and all candidates were forced to stand as there were no arrangements for seating or drinking water. Initially, only interviews were planned, as per the email. They began interviewing candidates with high experience and low current CTC. After another 2 hours, only those with less than 4 years of experience remained (approximately 30 candidates). At that point, they promptly decided to administer a written test, which included 6 programming questions. From those 30 candidates, none were selected. The programs were easy, and anyone with an engineering background could have solved them (e.g., swapping two numbers without using a third variable).

Swap two numbers without using a third variable.
