I went to the college campus fair. There an alumni took my resume. Two weeks later I got emailed by a recruiter. They scheduled me for an on campus interview. The dress style was business casual. He asked me three questions: What was my most difficult technical design challenge and why was it challenging. Write a function that will search a linked list for duplicates. Design an interface for a camera that will allow you to uploads photos from the camera to facebook. The questions were vague. For the programming question you need to ask details about the link list if it is singly or doubly linked. Then ask if you want to remove only consecutive duplicates or any duplicates. For the design question you need to talk about what the end user would do, how you can make it as automated as possible. Probably draw a functional diagram of the process. They expect you to ask as many questions as possible.
