If I know the companies, I don't need you anymore, why don't you mark a list of companies you think the user would be interested in and fetch the jobs for them. Now that's cool.
What if you don’t have to go to each companies individual website. Just select names of all the companies you like or know. The tool gives you a list of all the current jobs the company has posted. In this case multiple companies details all in one excel file.
Thus saving time on researching and rather focus on crafting your profile for that role.
Instead, the idea is to surface a small set of companies/jobs where you’re more likely to get a response.
