I am doing M.Tech structural it is my final year i.e. last semester, I have to apply for the job for which I have to write carrier objectives in maximum 200 letters.

Objectives are no longer put into resumes. They are a waste of space, telling the potential employer how the job seeker will learn and grow. The employer doesn't care about that. Objectives may be put into the cover letter.

Thank you for your answer. But there is a need to write carrier objective in separate page in 200 words. It is compulsory.

Then you must provide me with some words and phrases that are important for a future job. This is for structural engineering?

For example --
Are you able to apply structural engineering principles across multiple engineering applications, such as Aerospace, Civil, Marine, and Mechanical, in a rapidly changing technological world?

Do you possess ethical standards, and communication and collaboration skills essential to maintain professionalism in the workplace?

How will you help a company save money, and how will you help a company make money?
