Last year the company contacted me through LinkedIn (they initiated) and then after much delay did a phone interview of me. It was very obvious from the interview that it was a fake interview perhaps just to satisfy EEOC that they are interviewing people above 40. We talked for a few minutes and that was it.
I few days later I got an email from HR stating that I didn't meet their need but it will kep my file in mind for future needs. I wrote back stating that I have researched the company on Glassdoor etc and think it is a fraud company and asked them not to contact me again. That time stock was around 50+.
