These people are just a job shop, sending out job spam to as many people as they can possibly collect into their database.
A typical day at work consists of cross referencing a job description against a database of people that the company has illegally harvested, and, even if those people are only peripheral or tangential matches for the job, spam them. Repeatedly.
The hardest part of your job working for these people is looking at yourself in the mirror each morning.
It's better than licking up sewage.
