After 4-5 days I received a call and HR told me that, they are scheduling telephonic technical round. Next day around 1:30 pm I received a call from senior analyst, they asked question from probability, excel, VBA, sql and aptitude and reasoning, They took my interview about more than 1 hour and said they HR will call me and let me know about the feedback. After 3-4 days HR called and said that I selected and I need to visit the office for personal interview. After 4-5 days they scheduled my interview and I visited the office. It was more related to personal skill, than technical skill, it last about 30 mins, they said that HR will call me about the feedback.
