Conducted three rounds interview through out 2 week of time. Each interview goes around half an hour. After completing 3rd round they replied with normal slang of HR .. unfortunately... Actually it is waste of time for people who are experienced as bargaining salary and call for 3 rounds interview each dates as each rounds are getting completed by taking a leave of shift timing swap from current employer. Actually these company only call for interview but doesn't hire. Bad attitude , I didn't expect this from a US company.
