It was the most unprofessional experience I ever had. The interviewers were late by more than 30 mins, while I was waiting on the call. There were people on the call who were never a part of the interview. The interviewer, apparently a delivery manager had the attitude on a school teacher. I was scolded for using a pen and paper to write and he expressed his disappointment verbally when I couldn't answer a couple of questions such as, "How could you not know this after working for so long". It was more intimidating and imposing than it was about finding out the depth my experience. usesThe interviewer had a hard time understanding the projects I worked for and have no idea how product based companies function. He kept asking the same questions though I already had answered them like he has trouble understanding what I was talking about. And most of the questions were right out of a text book, seeking definitions that nobody uses. I am happy to not hear from these guys again, just like I wouldn't wish to go back to school
