Very fast turnaround. The recruiter called me for exploratory interview, set an interview with the department head based in India the following day. After the interview, the HR already informed me that the interview went well and that I shall expect the job offer within the week. After a week, I got the job offer.

Pretty Standard - STAR based. Hiring managers pretty much want to understand how you can add impact to their team/organization. Know your resume and be able to articulate your overall corporate experience.
