Insights:
Indeed has a lot of noise, with many companies being small and the salary levels may not be very high.
Major companies have their own recruitment platforms and systems. Often, you can use Indeed to search for companies and then upload your resume on the company's website.
However, Indeed has extensive coverage, so even though there is a lot of noise, it is still a mainstream platform for job searching.
Sometimes, headhunters also post job openings for their own companies, and when Indeed finds them, it navigates you to the headhunter company's website, where you can submit your resume.
Some positions at headhunter companies are contract to hire, which usually require a few months of contract work before being hired. These companies have relatively low turnover and are more stable.
