Worth doing an MSc?

Hey everyone.

I studied CS at an OK uni but basically cruised through my degree and didn’t take it very seriously. I kind of regret that now and have been contemplating pursuing a masters at Imperial/Cambridge.

I currently have a few yoe in HFT, so my question is - beyond just being whimsical, is there any benefit to me doing a master’s given the cost and career break? I don’t think my firm would pay for it.

Thanks
