Lighthouse Instruments Study Manager interview questions

The hiring process is not fair and does not reflect the truth.The interview went quite successfully from my perspective... However, today I learned that I am not even invited to a second interview. The reason given is a lack of experience in people management! but I don't find this reason very logical. I have over 7 years of experience in people management. IN fact, there was no clear definition or criteria in the job description for this.
