My favorite part of their story is how they changed the interview process to not be terrible and built a dashboard to quantify it: https://about.gitlab.com/blog/2020/03/19/the-trouble-with-te...
EDIT: More on topic, I did really enjoy the MR based technical interview way more than the common coding challenge.
They asked me to clone a rather large repo as part of the interview, I cloned it but it was slow, the dude just blamed it all on my internet and my geographic location. Like kept going on about it through the awkward slow clone. I think I wrapped it up early.
I ws cloning other repos of similar size and much faster speeds that day.
