Standard issue as long as it's one shift. It's only a con if we're talking long term and then I hope you realize what's happening after one week lol. Or even if it's more then two days without much competition for the position. Even 3 times is too much unless this is an elite entry level position and they're having their own playoffs with you and one other potential hire so to speak, but if it were that type of job this thread would have never been created and that is still probably a stretch. When I worked in the industry back when I certainly had a few of these, especially so because I am unschooled, but I've also seen this a number of times at a few places I've been in, even if only a mini version where the potential hire was asked to comeback another day during the lull to show their knowledge of certain dishes in action and then jumped into the frying pan for a couple hours of actual service, asked to step aside often when a true rush came even if they were doing well.
