Qualcomm interview questions

I got a call for a phone interview with one of the team members (Phone interview took place on Thursday) and since I mentioned to them that I already had an offer on which I was deliberating on, they expedited the process. 2 days after the phone interview (Tuesday), I got an email saying they would like to schedule an onsite interview, which I did as quick as possible (Friday). After the interview, I got an email from the recruiter saying the team would like to make an offer (on Tuesday) and in due course I accepted the offer.
