I was interviewed in Dec 2024.
She mentioned there would be a total of three rounds. I participated in two interviews; the first round went well, and I qualified for the second. The interviewer only asked me two questions, which I answered. I have been waiting since morning, and my interview was scheduled for around 4 o'clock, which is quite embarrassing. Additionally, I was given a task on which I had no prior knowledge and was told to complete it in one day. I finished the task, but after waiting 15 days, I was informed that I was not selected. On a positive note, the company is nice and even provides lunch during the interview, but I did not appreciate the selection process.
