What is gold for me is the business model that doesn't charge end-users, although I can imagine this might become problematic when the pendulum of the IT field's supply and demand for experience swings back.
I also like that the form doesn't ask for a PDF resume, meaning no more marketing and social engineering work for the ever-decreasing attention span of recruiters and ever-increasing automation in resume screenings. Further kudos for the straightforward interface and main form of the website.
Question though: how do you plan to combat spam applications? It doesn't seem that difficult to be _completely_ dishonest in one's application, which granted, will be detected in later screenings, but will probably shadow honest profiles.
Feature proposal: integration with major competition platforms to import one's stats (think Codeforces, LeetCode, HackTheBox, etc).
I hope this takes off well!
