- Older software engineers (40+) won't be discriminated against if they are doing cool stuff and are doing different stuff than they were doing a few years back. I've written this a thousand times before, but we often confuse ageism for stagnation. If you've had the same job for 15 years working on the same system and using the same languages, you aren't a victim of ageism as much as you are being discriminated against because they don't think you'll be able to learn new tricks.
- On resumes, don't advertise your age if you're a bit older. We don't need to list that internship, first job out of school, or graduation dates from college. List 15-20 years of your career and leave the rest off. It isn't a biography.
