Are you really suggesting that new developers should simply contribute a Linux tier contribution to open source to be considered for entry level developer roles?
I'm not sure how you missed 1/3 of my comment.
Clearly with such conditions it will not be an entry level job. Nor am I saying it's absolutely necessary. From what I understand a 99th percentile score on Leetcode will alone get you through the door.
Though a nice job (~40 hour weeks, good team, above average comp. package) with solid promotion prospects is about the maximum even a somewhat less impressive version of Linus could expect at 27-28.
