4 Stages, First phone interview, Second & Third Technical Interview, Fourth Personal Round (Still Technical Interview). You get noticed to the interview only one or two days before, and get the interview link on the previous evening. First round introducing company and making self description. Second round introducing past project, focus on project and technologies included. Third round talking more about project, but focus on other technologies other than the second round. Forth round still introducing project (coming the CEO not HR asking you about that, he has zero knowledge about you, even never seen your resume before coming), talking about details inside, which suppose to be a personal round.
