Applied as an SAP ABAP developer - Had to visit their campus multiple times over a period of couple of months.
First Round - They asked me to come over for an interview but after waiting in the lobby for sometime they called me into a meeting room and asked to give an online test. The questions were of moderate to very difficult questions - not sure how I got selected after the test.
Second Round - They asked to visit the campus again, this time I again waited in the lobby for more than an hour after which they said the interviewer is not available so they asked me to come again later(this happened 3 times). The final time they called, they called me into a meeting room and dialed into a person who took a quick 10-15 mins interview and asked me basic ABAP questions(mostly on Enhancements, IDocs, Reports)
Final Round - After the second round, I was immediately called into a different meeting room and had an HR interview with a person via Skype. Again, this was very short and they asked me my expected compensation.
