This blog post will be short and to the point. Often times, students apply for multiple internships so it's expected that they will accept some over others. This is absolutely fine. However, if you are going to take the time to apply for an internship and the employer emails you or calls you about your availability and potentially setting up an interview - REPLY TO THEM.
There is no excuse for not responding to an employer's email. Just because you cannot accept the internship doesn't mean that they still aren't a valuable contact for you. If they took the time to review your resume, take the time to get back to them.
