So you made it past your screening interview and are now into the second interview. Congratulations! This means that there was something in your resume and your first interview that your prospective employer found compelling. Now it's time to get ready for the second interview.
Tips on Your Second Interview
Your second interview will likely be conducted by the hiring manager.
Typically your first interview or 'screening' interview is conducted by an HR professional and not the actual hiring manager for the position. The reason for this is that screening a high volume of candidates is something that HR recruiters do on a regular basis, whereas the hiring manager is only responsible for hiring for his or her team.
The second interview will focus on more detailed questions.
In the first interview the focus was primarily on getting a quick feel of your job 'fit' for the role. You were probably asked informational questions, and questions about your resume. In the second interview you can expect the questions to be much more specific to the role that you are applying for. It's much more likely that the interviewer will use a behavioral interview or situational interview technique in the second interview.
You have to make a first impression all over again.
Don't assume that any goodwill you built up in your first interview carries over to the second interview, because for the most part it doesn't. The person conducting the second interview will have been given some information by the HR recruiter, but usually it amounts to 'this person is worth taking a closer look at.
The second interview is one of the most important steps in the process.
No part of the interview process is unimportant, but the second interview is particularly critical especially if it is the hiring manager doing the interview. This is the person who you will be working for on a day to day basis, and ultimately if you make a poor impression on them it is very difficult to recover.
