HR calls for 10 minutes and asks questions like salary expectations etc. After 2 weeks: 2 hours interview 45 minutes for test, including aptitude questions and technical questions. After that there is interview round with a team member, who asks technical questions. Then at last there is interview with manager, who asks technical questions and HR questions mix. Seemed like they were more concerned about salary expectation as the manager was asking about it again and again during technical round.
