Two sessions were held: * One with a tech lead engineer. * Another with the CTO and an HR person. Questions related to specific technologies (Java, Spring, etc.) and others related to architectures, among other topics.

The interview process consisted of three rounds. * The first was a technical screening with core Java and system design questions. * The second round was a live coding session focusing on multithreading and memory management. * The final round

A senior technical person called directly. I thought HR would set up the interview first, but I was wrong. He was nice and mainly focused on Linux kernel topics. You need to be dealing with the Linux kernel daily to be able to answer those questions
