I first had a virtual interview and then a week and half later they got back to me asking for an in-person interview. Everything went well. An offer was extended. I then tried to negotiate the salary by 4k and they rescinded the initial offer and said they made changes to the initial role (from Thursday to Monday). This is a start-up and after hearing this, it seems very disorganized and unstructured. This is a big red flag to me if they can't negotiate with you and don't seem confident in your abilities right from the start.
