There were 4 interview rounds. They took up a lot of my time and effort. I had to make a presentation too for the fourth round. After that I didn't hear from them. They didn't even reply to my emails. It was a complete waste of my time and extremely taxing.

Long interview process, interviewer is nice and engaging, it's going to be detailed and every aspect is going to be looked and focused upon. Overall decent experience. It was my first interview so got to learn a lot.
