 A job interview is a two-way street. When you're interviewing for a job, you're not just interviewing for you trying to persuade them to give you the job. You're also listening to see if you really want to work there. That's the key to remember. And so you need to ask good questions when they're at the end. Don't try to come up with that, hey, I'm the most brilliant guy on earth. Ask something you really care about because you might find out that the job that you're interviewing for would be a living hell when you got there.
