Average Positive Tel Aviv-Yafo

My interview path was pretty deliberate and spread across multiple conversations. I began with a general phone call with a team leader to get to know me better, then moved into a technical interview with two team developers. After that, there was an architecture-focused interview with the team leader and a group leader.

Once those technical and architecture discussions were done, I finished with an HR interview. The overall difficulty matched an average level: nothing felt like pure trivia, but it also wasn’t framed as extremely easy.
