Solvency interview questions

I have applied for the job through job portal and got selected for capital one client. Later I have got the interview call within the 3 days. There were 2 rounds of interview, the first round was moderate where as the second round was pretty difficult with some coding questions involved. These two rounds took me 5days. I was selected for the job and have received the job offer in just one day. All of this process took me like 8 to 10 days.
