"Trial and error. Give him or her a UI component to redesign, or present a problem you’ve been facing and ask for some ideas on how to solve it." Asking for ideas is cool. But I don't personally agree with having to re-design something on the fly for them. If I don't come up with the ideal solution in a short time, I don't think it should make-or-break the job. Design needs time, just as much as any other craft. Actually, I remember one company offered to interview me after viewing my portfolio. They asked me to re-design a news website as a test. Since they are a really big firm and well-known agency, I did it. After seeing two iterations, they rejected me. I eventually got a job at another well known agency (without having to do any tests). Funnily enough, the news agency whose website I had re-designed in that previous interview test signed up with the agency I was currently working with. Thus, in the end, I ended up actually doing the real work.
