Selec Embedded Engineer interview questions

In response of posting my CV I got an interview call. When I arrived there, no body was there to whom I can ask anything, only the security personal asked me to sit and wait. After waiting about 1 hr, met someone (probably a new intern) who handed over me a question sheet and some blank paper (though I was experienced, it was the prelim test). Then the HR came and in HR round Im being asked why I want to leave my current employer, what is my expectation etc.. then they took me to a lab and gave 5 Embedded C programming problems and I had to compile those and run in their given hardware (8051). After completing that, the technical round was taken.

First we had technical apti, in which most of the people were eliminated. After that we had personal interviews with technical head. And then at the end only 3 people were selected for final interaction with founder of company after which me and my friend got selected
