Call the agency or company if it’s an internal recruiter. Be prepared to answer questions on the spot about your experience and resume. Answering these questions well might get you past the 250 other resumes and straight to an interview.
If you don’t get to speak with the recruiter, leave a message and follow up with an email and connection on LinkedIn. This is the first step in establishing rapport and a relationship. When leaving your message, be considerate and avoid coming across as demanding or entitled.
