The process was nothing but a disappointment since I had a good impression of AppDynamics before interviewing with them. The HR called to schedule an interview but failed to give confirmation on a time to me. When it was finally rescheduled, the interviewer was very weird. He has a set of questions and would give me exact 10 min time while he goes away god knows where. He would come back after 10 min and ask me if I have solved it completely. If not, he would move on to the next question without even having a look at my work or discussing the problem. Whenever he did speak, there was a child crying in the background(it was a telephonic round and I guess he was taking the call from his home). They might as well have sent a hackerRank link if all they wanted was a binary answer. All in all, a very horrible experience.
