This was my second interview with Intel, following my phone interview. It was a face-to-face meeting with four members of the group I would be working with.

They primarily asked programming questions, mostly basic and fundamental concepts in C, such as:

• Pointers and the difference between '*' and '&'
• Call by value versus call by reference
• Array lists and loops

One interviewer reviewed my resume carefully, going from top to bottom and asking questions about my projects and work experiences where appropriate.

I couldn't answer most of the programming questions, as I am not a professional programmer and it has been years since I did some coding.

I'm still waiting for their answer.

If we have a string of 7 characters, and we can put any character from 'a' to 'z' in any of these places, write a program whose output is the sequence of strings from 'aaaaaaa' to 'zzzzzzz'.
