I applied through a consultancy. Simple process.. Mainly they check your english skills. Be confident and relaxed. Its only based on your English skills initially. The first round was to tell about your self where the HR just checks on your communication skills. The next round was a telephone round just to see how you speak and understand over phone. The next rounds are based on SQL. Again simple questions and basic ones. Joins, cursor, trigger, stored procedure. The last round was a round with manager. Basic questions like how to find ipadress, joins, triggers, stored procedures, 7 layers of osi etc. And finally the US manager speaks to you just checking your communication skills.
