Practice Active Listening

Pay close attention to what your interviewer is saying, so you can get lots of information out of the first interview. You'll learn more about the company, its business structure, and the different people with whom you meet in the interview. It's important to remember that you'll remember more of what you hear and discuss during the interview if your nerves are under control.

Active listening is critical to being "in the moment." Not only does this promote strong performance in your first interview, but it will also help you prepare for the second interview.

Take Notes during the Interview

Don't spend all your time scribbling notes in the interview, as this will be a distraction for both you and the interviewer, but do take some notes in order to jog your memory later. You should make note of the interviewer's names, job title, and role(s) in the company. Notes taken on the organizational structure, business operations or any major clients mentioned in the course of your conversations will help you later, as well.

Not only is it important to have the information on various aspects of the business and the key players in the company to help you recall details before attending a second interview, but you'll also be able to do some additional research that will help you have a higher quality conversation. Researching a company, the individuals with whom you meet, and the specific job for which you're being considered all help you elevate your performance during an interview, whether it's the first or the final. Other topics that you can do follow up research on include:

Business challenges that you learned the company is facing, which you can use to formulate how you can make direct positive impact in those areas.
Company initiatives mentioned during your first round of interviews which you'd like to get more details on; this shows an interest in the business and that you'd be a fully engaged employee.
Areas of your knowledge about the job, company or industry that you identify as weaker, based on your comfort level of these areas in the first interview.
