Hopefully you’ve done some research and you know the company only has 10 employees or it has a development team of 150. If you’re moving from large to small or vice versa it’s probably good to show that you know what you might be in for. If you like a nice subsidised canteen and powering your machine down at 5:30pm, then a 10 employee company might not be for you. Be prepared to talk about the environment you’re expecting and how environments you’ve experienced in the past have worked. How do you see yourself fitting in? Do you understand how IT projects tend to work in smaller or larger development teams?
