Cisco Software Development Engineer interview questions

Interview was average. Interviewer was not that co-operative. Overall I knew the answer so explain quickly and the interviewer were satisfied. In the last question I got stuck and struggle for few minutes but they didnt help me.

I have applied for 10 different positions. And I have been invited to an on-site job interview for one of them. On the same day, I had a technical interview with 3 different people.
