This is true. During my tenure at Lilly my DM only hired younger individuals in their 20's. I was the last "older person" to be hired and I'm only 38. The 5 people after me were all in the low 20's. I noticed the same trend with surrounding districts too. It's really not fare (please spare me the life isn't fare speach).
Each time there was an open position on my team I reached out to my DM and gave him some solid references, but nope, he went with the 22 year old every time. I'm worried what happens when I'm 45 or 50 or 55 or 60. There's no way a pharmaceutical will hire me over some 22 year old that was captain of the cheerleading squad in college or some football star. Ugh
