When you prepare answers to commonly asked interview questions, such as those about salary expectations, it's important that you provide the interviewer with information that you feel comfortable with. This, however, does require doing some research because you should be able to elaborate on your salary expectations. On popular websites such as Indeed or Glassdoor, you can find a lot of free accessible information that can help you determine a salary range. However, remember that salaries may vary due to different factors, such as geographical location, work experience, and other qualifications.
