Many international students are turned down after they are interviewed. There are many reasons for this, including missing qualifications, lack of work experience, lack of knowledge of the business, cultural differences, the language barrier, and so on. It is understood that most interviews do not lead to a job. It is usually necessary to make many, many attempts before you finally get hired.
Many people feel that looking for a job is much harder work than having a job.
But the last place you try will be the one that hires you. Often, you are expected to educate the employer about these details, possibly during your interview. This is crucial for any job hunt. You must understand what the company does, who their competitors are,what they are hiring for, and what qualifications they are seeking. Your Career Center library has many resources to help students research employers.
