There were 4 rounds total. 1st was HR round, 2nd was technical round which consist of sql queries, 3rd was telephonic round in which they asked about database comcepts suchas what is index, views or programming concepts such as abstarction or interface. Final round is Manager round. This is a mix techinical + HR round. Just make sure in this round if you are very much passionate about development dont show much interest to them. Just make sure stick to the data migration profile and say I want establish my career in data migration field only.
