A lot of what gains you points in an interview is your behavior. They already have your resume. They want to know about you.
Wait for the handshake: The rules of a handshake have changed as more women have entered the workforce. Normally, two men should shake firmly. Beyond that, you’ll have to use your judgement. Don’t crush a person’s hand. Practice with male and female friends.
Keep standing: Don’t sit until you are directed to. There may be other people participating in the interview and it’s best to show that you are “open to direction.”
Make a good first impression and maintain it: Mirroring is a powerful technique if used subtly, no matter the interviewer’s mood.
Remember what it’s about: Think “what’s in it for them” not just “what’s in it for me.” Both parties have to benefit.
Be prepared to get tested: you might be asked to prove, say, your computer programming skills with a small quiz on basic principles of coding. Interviews for other industries might include similar testing.
Closing and Post Interview
The end of the interview is just as crucial to getting a job, as is what you do afterwards.
Know your availability: An interview may ask when you can start. Don’t be afraid to say that you have a vacation scheduled, etc., or that you can start immediately.
Be flexible on salary: When asked what you’re expecting, a good answer for a new grad is that you’re hoping for at least fair entry level wages, with performance bonuses. You might even say that you’re willing to accept stock options, especially at a startup.
Ask for the job: If the interview goes well and you think you want to work there, ask for the job. Say something like, “Well this sounds like a very interesting job and I’d love to work here.” Do this when they offer their handshake goodbye. If they like you, you’ll be asked back for a second interview, or you might get offered the job right there.
Say thank you: Thank the interviewer and the receptionist, etc.
Be patient: As you’re leaving, ask about the selection process and when you might hear back. IF there’s more than one position, you might hear back sooner. You might get more than one interview, but that may require sign-off from someone on vacation.
Follow up on each interview: Experts offer differing opinions on this, If in doubt, call reception and ask their suggestions, especially if you haven’t heard back within two weeks.
Keep an interview log: It’ll help you track the state of each application (sent application, pending interview, interview complete, followed up, rejected, etc.). Include dates.
Keep learning: An advance degree may help your career, but you can also learn without returning to school. Many large universities are offering their courses free online.
