They called me thru hiring company. I gave all the details of my current work and skill on phone then they called me for interview. Interview question was pretty simple and generic one.They also showed me their lab and different type of machine on which embedded system coding was done.They asked me if I have any question . After one week they called me for second interview. In second interview I met with HR and Head ,It was very formal meeting.They gave me offer letter after one week.
