I applied through Internshala and, about fifteen minutes later, received a message stating that interviews would be conducted between 10:00 am and 5:00 pm the location of office was near Delhi Gate metro station. It was clearly a mass message, sent to all applicants.
I arrived at the office around 11:00 am. There were already a dozen or so candidates waiting for the same position, and more were arriving. The interview itself lasted approximately ten minutes.
During the interview, I was asked if I had my laptop with me, even though there was no mention of bringing one in the initial communication. They proceeded with the second round only for those applicants who happened to have their laptops with them. The rest of us were told we would receive an email if we were selected.
