While a very lengthy interview process (5 stages + a technical test), everyone was lovely to talk to, and each interview was a very natural conversation (rather than feeling like a Q&A or a list of questions that needed to be asked).
There was a large focus on making sure that not only I was a good candidate for the position, but also that GAN (and the position) would be a good fit for me as well.
The wait time between interviews was never more than a few days.
