That's discouraging for someone who is trying to switch to a NetSuite specific job. I guess the easiest way is to get hired first in a NetSuite position.

Yeah but nothing beats having direct real world experience in a platform. A good developer would adapt to learning NetSuite but most employers are not going to wait for them to get over the learning curve. The only simple option for your friend is to go the salesforce.com route and invest time there. Salesforce.com has traditionally had a bigger ecosystem than NetSutie which means more job opportunities
