Generally, private enterprises are carrots and pits. If you have the ability, you can continue to work. If you are not competent, you can leave the office at once. The general process of our company is that the department applies for recruitment, and after the boss approves it, the human resources department starts to recruit information according to the requirements of the department. After the interview is passed, the department should sign the employee acceptance form. In the first three months of the probation period, the department head will keep in touch with the human resources department to communicate the work and performance of the newcomers to see if they meet the employment needs of the department. As you said, many times, your colleagues or department heads around you observe that your work attitude doesn't meet their expectations, or you disclose your thoughts that you don't intend to do to your colleagues around you to let them know, so in order to avoid the job vacancy caused by your sudden resignation, you will release the recruitment information first. Of course, there may be another situation: there are two people in your position. The first one is that you have already joined the company and your performance is OK. If you need to recruit another one at this time, the recruitment information will be released in advance.
You can consider what kind of situation you are and make a judgment. I hope I can help you. I am a small snail guarding my position.
