Enjoy the moment and celebrate your graduation, but after a day or two it’s time to focus on the next task at hand: getting a job. If you think that getting through college was the hardest thing you’ll ever have to face, then guess what: You’re wrong!

Interviewing for a job will be an even bigger challenge. At least in college there’s a syllabus letting you know how to get a good grade. When you come in for an interview, you never really know what it will take to get the job.

The best that you can do is to prepare ahead of time and avoid making mistakes. Here are a few of the more common mistakes to look out for.

Unenthusiastic and uninterested – Whatever the reason you have for not being excited about the opportunity is hurting your chances of getting the job. Your level of enthusiasm will show, and if you don’t show it in the conversation, the interviewer will immediately see this as a sign that you don’t really want to work for the company.

Not being able to tell why you want the job – When you just graduated, you might not know what exactly you want yet. Maybe you just blasted your resume to a bunch of random companies that look great to work for. Then, when the interviewer asks you why you want to work for them, you just mumble a halfhearted answer. When you truly want something, you need to know everything about it—and this applies to a job, too.

Clueless about the company – When interviewers take the time to speak with you, they expect an applicant to know about the company. Why? Part of it to make their job easier, as they don’t want to explain it over and over again to every applicant. Another reason is to make sure they get someone who cares about the company like they do and will do his or her best to work hard for the betterment of the company. So, if you come to the interview not knowing anything about the company, it shows that you don’t really care.

Can’t explain why you would be a good candidate – A resume should be a great indicator of your abilities, but if you can’t explain it verbally, it won’t be enough. Don’t feel bad about promoting yourself, because the interview your one shot at explaining why you’re the best applicant. If you don’t do it yourself, who else will?

These mistakes are just some of the more common ones made by fresh graduates. When applying for a job, you might not have the luxury of experience yet, so it’s better to arm yourself with this knowledge in order to have a better chance at getting the job.
