I went to one of their launch events and saw a NN being trained live. Having said that, it was a SNN and I was a little surprised as to why they chose to do that instead of a standard NN.

I felt that it looked appealing, but my biggest problem with it was that you needed a special version of pytorch (and Tensorflow, I think?) which always worries me. It's not easy to pull the two repos together and I'd rather not have an entirely separate repo just for my GPU especially when the two can get diverged

I've had good success with cover letters WHEN I've actually had interesting things to say. Without a control it's hard to say, but I got interviews for companies and roles that were far out of my league this way. However, forcing candidates to write cover letters is completely pointless and wastes everyones time

When you mention remote-flexible do you mean that you can work within one of the corresponding countries, or do you mean worldwide? Also, I'm guessing visas aren't supported?
