The interview will mainly examine Java foundation, middleware principles, and project experience. The interview duration is 30-60 minutes.

The scope of the Java foundation and middleware investigation will be attached at the end of the article.

For project experience, please choose a representative example. A representative project is one that is highly relevant to the job you are applying for and is of moderate difficulty. It is advisable to ensure that your explanation takes about 10-15 minutes. If the project explanation is shorter, other aspects, such as Java basics and middleware principles, will be investigated in greater depth, increasing the interview's difficulty.
