As a student navigating the job market, I've found LinkedIn increasingly frustrating due to numerous fake postings by consultancies. In contrast, this job posting website has been a game-changer for me. It offers genuine opportunities and a straightforward application process, making it much easier to find and apply for real jobs. Highly recommend it to fellow students seeking reliable job listings!

Echo Jobs has been exceptional in my job hunt where it provides one platform to job hunt and I don't have to open 10 websites just to look for a job. It has also helped me focus much on the job skill and the location filtering out the onsite jobs and remote ones. The only feature that I would request is to display fully remote jobs that are not restricted to a country since the one available shows ie, Remote, US yet. But if it could show remote only, that would be helpful not only to me but to other people applying for full remote and not tied to only US candidates

I found EchoJobs in 2022, and I love it. It has a lot of remote jobs. It's exclusive to software and technology jobs (helpful for devs like me). What I like the most are its filters and its API. If you're a tech professional seeking remote work, I highly recommend giving it a try to EchoJobs.

Simply put, it's the most up to date tech jobs aggregator I’ve found. I'm like... "I don't have to check 10+ jobs boards daily just to see if there's a new job listing? sign me up!" The filters are also quite helpful! The UI is very clean and straightforward. Love it!
