> Oh, wait, now I need to deserve a job
I didn't say a job. I said the job I'm hiring for.
If you're going to come in and deliberately do as little work as possible to extract as much as possible from the team, why should I give the job to you instead of someone who is actually honest and cares?
You're not entitled to any job you want, obviously. I usually have 10-100 applicants who would honestly do the job and not sandbag their work onto peers. Obviously we would all rather have the honest employees working on the team.
In what moral system do you deserve the job more than literally any other honest employee if you're dead set on doing less than them and lying your way through the job?
If nothing else, having two jobs becomes a conflict of interest with a huge monetary incentive to continue lying. There's also the matter of trade secrets as people often come from related companies.
