Kaggle for Quant research roles at HFT/prop trading

[jabran]

For entry level Quantitative research roles at prop HFT firms/quant hedge funds, how do good firms view Kaggle rankings ?

As we know the these roles are extremely hard to get, and you need exceptional achievements outside the STEM degree, does a grandmaster title on Kaggle count as exceptional achievement ?

Is spending 'lot' of time to achieve high Kaggle ranking and proving myself there worth it if the end goal is QR role ?
Second question, do you think is grandmaster title alone is good enough to get foot in the door if someone is changing career ?

I know the skill gained on Kaggle is valuable in general but the question is purely from the point of view of QR recruitment.

Thanks
