The GP is unclear as to whether the loan happened before or after the friend obtained a job offer. Loaning moving expenses money to someone who just got a high-paying job offer and needs the moving money to start the job does not sound that risky.
Agreed, though you have to wonder why the company involved couldn't do this more formally?
It is worth wondering about that. My first job out of college offered an interest-free loan (paid back by paycheck deductions over 2 years) for moving expenses.
