Completely agree with @cgsmith. I did an internship at age 30: it was 2008, the economy was in the doldrums, and I was desperate to change the direction of my career. The internship lasted 6 months, I was obviously far more experienced (in terms of strategic thinking & organisational experience) than other interns, my boss and even the boss of my boss. Long story short, 6 months later I was hired by the company with a decent position, salary, and having completed my professional turnaround.
