Infosys Senior Software Engineer interview questions

I applied through their career portal directly. After 3 weeks I received an invitation mail from them for a face to face interview. Same week Saturday it was scheduled. There was three persons from Infosys and they were pretty good in behavior. Interview was went so good and they told me at the end they would love to work with me and HR would inform me for further process. On the very next day Sunday early morning I received a mail from HR asking about few documents for further process. I submitted that on same day and again very next Monday I received a call from HR for salary discussion and bang on. Same week Friday I got my offer letter.
