Generally, there won't be much problem. But it also depends on the rigor of the company you are applying for and the position you are applying for. The bigger the company, the higher the position applied for and the stricter the requirements. If it is only some basic positions, the high probability will not affect your entry.

It won't be a big problem. Almost everyone has secrets and experiences that they don't want to be discovered. This is normal. Companies will also understand this when choosing employees. What they value more is the ability of the employee and the value he can create for the company. The greater the ability, the higher the willingness of the company to accept.

If you only apply for some basic positions and do a good interview, you should be able to join the job smoothly without worrying about concealing your work experience. Although the company wants to check, it has a high probability of finding it. But the company will not give up an employee easily because of three months' work experience.

The higher the position, the more dangerous it is. But if you apply for a higher position, it will have a direct impact on the company's decision-making and development. Maybe the company will be more concerned about the fact that you hide your work experience.

Generally speaking, the company will talk to you about why you want to hide this experience. As long as you haven't made any mistakes in principle during this experience, you will be able to join the company smoothly with a high probability. After all, there is no more unified reason for people to go out to work and choose to leave quickly. After making it clear, it shouldn't have much impact.
