Spectrum interview questions

Phone Interview with a Recruiter. 2nd F2F interview with 2 recruiters. 3rd Interview with the Hiring Manager. 4th Interview with the Director of HR. I'm ok with not getting this job, but have the courtesy to call someone and let them know. Don't say you'll follow back up. I emailed the recruiter 5 days after my 4th interview to touch base. No response. I called her two days after that. I knew at this point I more than likely didn't get the job. I got her voicemail so I called the Director of HR with whom I had a phone interview with. I was informed at that time they had gone with an internal candidate. That's all ok. BUT, HAVE THE BALLS TO LET SOMEONE KNOW! I'm a candidate with many years of experience. I deserve better than this. Heck, we all do. STAY AWAY.
