What is a start-up company?
A start-up company is a newly established or developing company that has just come into existence.
Many companies are trying to provide new value to the traditional market by using unique ideas and innovative technologies.
Unlike large companies, because it is a newly established company, the president is sometimes the only board member, and because there are only a few employees, the company has an open atmosphere, and it is easy to express opinions to the boss and have them easily passed on.
On the other hand, startup companies have a high-risk, high-return nature, and although they may earn huge profits, they may not be well recognized and their compensation may be insecure.
In addition, the working environment may not be deployed, and the newly established company with few employees may not be able to make life routine.

What is a major company?
Large companies are organizations with capitalization or total investments exceeding a certain size and a large number of employees.
These companies operate in a wide variety of industries, such as manufacturing, construction, and transportation, and are characterized by a clear organizational structure.
This gives you the opportunity to learn not only engineering skills, but also management skills when you are promoted.
In addition, because they are well-known companies, they are highly reliable and have the advantage of receiving a large number of projects and jobs.
Because management and capital are stable, compensation is also secure, but on the other hand, the clear division of roles can make it difficult to gain experience as a full-stack engineer.
Furthermore, while the work can be done with care, the work speed can be slow.
