“I get the impression that they didn’t read my resume!”
It got read, maybe partially, but not studied and memorized. Understand that you are much more invested in your resume than the hiring professionals reviewing it.
While having a well-organized resume is essential, understand that it’s simply a marketing tool. Its primary purpose is to get your foot in the door with a company. It’s not your entire presentation, nor a substitute for explaining and highlighting your skills. Never answer a question with a comment like, “It’s on my resume.”
The interviewers you’re meeting will have scanned it for highlights, indicating that you might be the right person for the job. They will get to know you better during the interview process.
Your resume is your marketing brochure. Your interviewing skills will ultimately land you the job. So when the company expresses interest in you, be happy that your resume has served its purpose. Then get focused on the interview.
