If you do not receive a response from the organization in a week or so, or shortly after your thank-you letters have been sent, it is appropriate to email or call to inquire about the status of your application, unless otherwise directed. At the end of your interview, you should ask about the hiring timeline; if you did not, you may email your contact to inqure of the process moving forward.
You may be asked to come back for a second or third interview. Later interviews will concentrate on more specific subjects regarding the position and your skills, and you may discuss salary, benefits, bonuses, and options. Remember to only address these issues if the employer raises them. These interviews may involve a tour of the organization, interviews with staff from several areas of the organization, and possibly tests or forms to complete. The interviewer should give you this information in advance. If they don’t, it is within your rights to ask.
