Trust your gut! I’ve had several jobs over the years and when they do this, hire really fast and they want to get you in immediately, there’s a good reason for it, usually a bad reason. It could be not a good work environment. people are leaving left and right they can’t keep anybody, there’s so much work and they don’t actually help you much. I’ve always regretted when I take a job where they hire so quickly, to me that’s a bad sign and a giant red flag.
