Crossover for Work Chief Software Architect interview questions

I applied for this position & hiring process is strange. They have 5 online stages for different kind of tests, & every round seems to be elimination round. As I didn't get through the second stage of CCAT. So don't know about further stages. But not sure what they are trying to understand with CCAT.

Local hiring tournament that had place in Sao Paulo. Had a 3 stages with people getting dismissed after each stage. Took almost a whole day long. English / code review / programming.
