Since we are all lives on on world, we have common sense of reliability. And if something is looking more reliable then other we chose it. So and with job seekers and job posters.
Let imagine situation where top-notch candidate got 2 suitable jobs from 2 companies.
And time to chose what company will be his future. Let`s see.
He opens up first job posting, hmm…
Actually candidate like this offer, big company, big salary… but who is employer? Oh, it is so pitty but there is only email of some person… And in additional registered on free resource.
And now our candidate goes to another job posting
Whoa!… IT LOOKS BETTER. Now candidate wants to see company`s profile
And candidate finds out everything he needs about this company, where he/she can call, where main office is located, he knows short story and description of company.
In real life we all have to take a couple of days of break to choose where you will work, since you have several opportunities,
but most likely candidate will stop on second offers, even if both companies have the same jobs,
and you know why:
EXCELENT MADE JOB POST IS A KEY TO CLOSE VACANT PLACE.
