I interviewed for a position with one of their Smart TV software development teams. They gave me a simple-ish problem to solve. It needed to be C++ code, it needed to contain no mistakes (although they wouldn't give me a list of what they'd consider "mistakes"), and it had to be done in a plain text editor while talking to the interviewer on the phone. I took from their "perfect on the first try" requirement for interviewing that their strategy for handling technical debt was supposed to be "don't create technical debt".
