Communication during the job search process is very important to successfully securing a position.  As soon as a hiring manager contacts you for an interview, your communication style and approach will be evaluated also.  There are two key components to consider when contacting anyone in the company you want to work for; method of communication and content.  Here are some tips for different situations:

• Scheduling the interview - If you missed the call to schedule an interview, the best way to respond is to call the person back asap. If you need to leave a message, be sure to request a call or email back to confirm the time/date for the interview. Give the hiring manager a couple of options for the interview unless they only provided you one in their message.
• Confirming appointments - The day before any interview - phone, video, or in person - it's crucial to call the person who scheduled with you and confirm the time and method. This is especially important if you and the interviewer are in different time zones. Don't do this via email - you want to speak with someone personally so there is no miscommunication.
• Following up - After every interaction during the process, you need to follow up via email to the person. This includes any administrative personnel who have assisted you in scheduling. Keep these communications brief and showing appreciation for their time. In follow up to an interview, be sure to remind the hiring person what you discussed and the experience you have that makes you the best candidate for the job.
