feel like i fucked my career (mid level)

was an swe at one of the big name but mid rank HFTs (think Tower, IMC, DRW, SIG etc.). left without another role lined up to prove myself that i could get to the upper bracket; felt like what i was doing at previous firm was easy

blew about 25 processes now (couple of offers from equivalent tier places). usually get to final stage. i dont have any targets left so currently sitting on cooldown. pretty concerned that ill now be in the black book/reject bin of more or less the entire industry, and am having a crisis of faith of whether i even am supposed to be there

anyone gone through something similar?
