For Toronto in-firms, a number of firms have Monday dinners and you can only attend one. Some firms also offer Tuesday interviews, so you can max attend 2 dinners. If you tell a firm you won't be able to attend their dinner, how screwed are you with that firm? Is it even worth interviewing with a firm that you've turned down a dinner with? It seems a bit silly that your chances would be shot given how many firms are having dinners, but I am interested in anyone's thoughts/experiences.
Thanks in advance.
