Interviewer was sucks, he was not knowing the fundamentals of data structure. I had cleared written and one Skype round.. then they asked o come down to their office. I went there and Interviewer First started with questions on why do u want to do job changes. After this he asked about project, then they asked android life lifecycle and fragment transactions. I answered (obviously). Even my Skype round was more standard than this. Then he asked to reverse stack, i answered, he was not satisfied with my answer and went out.
