I am seeing quite a lot of posts nowadays in linkedin with people posting about their recent results in contests, thanking everyone for that, most headlines are now 5* in codechef | Expert in codeforeces. it's just frustrating to use LinkedIn nowadays.
Some post templates I have seen:
I solved a codechef long problem after 3 days of struggle.
I participated in xyz-platform's xyz contest took world rank of 100, I thank everyone for that.
I am delighted to share that I am now a 6* coder in codechef.
What's the point of sharing them there? Is this a humble brag to get interview calls?
