What I said was not based on assumption nor a generalization.
I have seen people at the age of 30-32 being recruited in 2006 when there was a huge demand for professionals in IT industry and there was practically no contribution from them to the team. Reason being they were not socially comfortable working with younger people who were all just passed out college grads aged around 22-23.
Eventually they quit after 6 months and joined other companies adding fake experience.
Again let me say this is what I have seen happening when I was working as a fresher. Things might not be the same every where with everyone. Some might be motivated and stick to their job.
