While there is a degree of ageism in the industry - avoid companies that advertise their ethos as "work hard and play hard" because having to do most of your office politics half-drunk in the bars after work is not much fun - there are also a lot of people in the industry who genuinely care more about a person's ability to learn and adapt than the date on a birth certificate. Believe in your abilities. Wishing you good health for the future!
