This is one of the worst interview processes in my career. They will ask you to write an essay literally, full of behavior questions tracing back to your high school (why???), like how did you do in Math and Physics; What are your favorite subjects? I wonder if they really need a senior dev or just a new graduate. Expect to spend 6+ hours answering those meaningless questions. After this, there is a "standardised aptitude assessment" to test if you are a normal person. "The GIA measures reasoning, perceptual speed, number speed & accuracy, word meaning, and spatial visualisation." Preparing to waste another hour on this, and asking yourself why I am doing this.

I understand they are looking for a very specific type of profile. It's just not for me and after a long form with 30+ questions, some of then about my teenage years hobbies or my grades in school, and a intelligence tests consisting on sesame street knowledge like "Peter is taller than Jenny. Who is shorter?" i just withdraw, if that is the respect they have for candidate time i am not a good fit for their culture.
