The initial HR contact was very pleasant and they wanted me on board in less than two weeks. The interview with HR and the first two levels went very well. HR negotiated the salary and finally decided another level of interview with someone from India. I cannot recall anything that was unusual. Luckily, despite the pressure from HR, I did not submit any notice to my current employer, as I insisted on obtaining a Job Offer Letter. However after a frenzy of interviews, a lull of two days was disconcerting. Finally I received an email stating they were reviewing other resumes.
