I am very confused now, and I ask for advice from people who have experienced it. I am a senior now and have come out to work. Just signed a company, and the salary is not too high.

Apart from the salary, are you satisfied with the job itself? If you are not satisfied with your job, I suggest you change your job. If it's just a question of salary, I think you should accumulate some experience. When you have certain experience and qualifications, it will be easier to find a job, and you don't have to worry about salary. This is only my personal opinion, and it has only reference value. Actually, it's better for you to make your own decision.
