That is the second-shortest job application form I've ever seen. (The shortest one asked for a name, email and LinkedIn without a free-text field. I think "who are you" is more important than "name".)
Yea right! People seem to like it :) the last one I posted here got more than 200 applicants, many curious, great minds here. Could the job ad be connected with how companies are building product?
I like the brevity of it, but I don't like the assumption that every good candidate will have everything that they want to share with a prospective employer on their LinkedIn page. Something like "Link to resume, LinkedIn, GitHub, etc. (whatever you want to show us)" would be more inclusive.
