In CA, you “could” get away with 5 job applications to show the gubmint’ you are out looking for a job. My EDD buddy who works for the State that with the amount of people applying for E/U I, it’s close to impossible to verify if the recipient did apply for the company that he wrote down. FYI, the job training courses are nonsense.
In WA state it's 3...5 would make it even more likely people will apply for the minimum so they don't run out of real jobs to apply and claim for each week. The system subsidizes a prolonged search.
It is probably nearly impossible to check on the validity of claimed applications. I know I've always reported the truth on where I've applied when I was on unemployment...obviously not everyone has the same tie to honesty.
