I was selected through Amcat and after that PI and HR round were there. After the PI round a number of tasks were given to different candidates such as Digital marketing campaign or graphic designing. They also tell you to make some calls and help them in sales. My overall experience was that I learned a lot from this interview thought do not select in a go but take a lot of time with their results.They might also tell you to sell them a pen. They also ask basic questions on what is IOT and Artificial Intelligence.
