When you are lucky enough to have a job interview, you will want to be as well informed about your potential employer as possible. This will show the company that you are serious about working for them. Think about researching the following, and begin to shape your possible responses to questions according to what you learn.  What is the company's mission statement? What are it's objectives? What skills and values does the company look for? Who are the key players in the company? If you are told who will be interviewing with, try to find out a little bit about their background. By doing this you can hopefully identify a few questions before the interview takes place. This will give you and edge when the questions come up. Some common interview questions include the following:  Tell us about yourself? You will not want to be too wordy with this response, a one minute response will do. Why did you apply for this job? Be honest, and tell them what is appealing about the job and the company. What do you know about our company? Draw on the research you have done on the company. What questions do you have for me? You might ask for more details on the day to day duties of the position, the growth of the company, or your potential for advancement in the company. While some of the following suggestions may seem basic, they play a key role in making a good impression at an interview. First, you should show up 5 minutes before the interview; do not show up too early, and never be late. Secondly, appear well dressed and carry yourself in a professional manner. Finally, arrive prepared with a pen, paper and several copies of your resume in case they are requested. Always dress professionally even if it is not a professional position. Avoid shorts, flip flops, jeans, and other casual attire. This starts when you greet the interviewer with a smile, handshake and direct eye contact. You will want to carry this good start into the interview room, where there are several points to keep in mind.  Make sure you do not slouch. Do not break eye contact during conversation. However, be mindful not to stare. Do not cross your arms. Instead, keep them open in a friendly manner. Avoid fidgeting or touching your face. All interviewers are different. Some may be relaxed and even casual, while others will be very serious and professional. If you find your interviewer to be formal you should match this. This will create a connection between you and the interviewer, and he or she will feel that you have something in common. This will help to show the interviewer that you are interested in the company and the job. You may want to ask questions about employee benefits, employee experience, room for advancement, or the next steps in the hiring process. Regardless, ask questions that demonstrate that you are familiar with the company and the job. For example, if you read that the company recently won an award or a new client, mention it. Some interviewers will let you know their timeframe for a decision. If they tell you two weeks and two weeks has gone by, you should send a polite email confirming you are still interested in the position and asking if they have a decision timeline. If you were not told a timeline, you can send a similar email after about two weeks.  Keep the follow up emails brief and polite. Hiring managers are generally very busy, so try and be patient. Try a note that looks something like this: "Dear Manager, Thank you so much for meeting with me today. I enjoyed learning about the company and the position, and I am very excited about the prospects of joining the team. I look forward to hearing from you about the next steps in the process."
