Data Path interview questions

At first they contact with me to sit on a written exam. After 3-4 days of written exam they called me for their interview. The whole interview divided into two parts. One for your personal interview section and another for the technical interview.

They asked us for an interview on a certain date and after reaching office the interview process went on for about an hour and a half. after that session a call was given after 2 days and was asked to take the appointment letter.
