Employers tend to organize work around blocks of time: the morning meeting is from 10 to 11, the orientation lunch is from noon to 1, and so on. There's nothing inherently wrong with that -- throw out the schedule entirely, and workers lose the pressure and relief of knowing exactly when their part of a project needs to be completed. But recent research suggests that concentrating on the clock at the expense of the task might make workers less happy and creative in the long run.
When preparing for a job interview, it's easy to spend so much time practicing answers for questions the interviewer might ask that you neglect to think about the things you'd like to learn about a prospective employer. Don't make that mistake: come prepared with the right questions, and you stand a much better chance of figuring out if you'd actually be happy working for the company on a day-to-day basis. Just make sure you don't ask any of these.
