Unprofessional Experience!!
Unfortunately, the panel's behavior during both rounds was highly unprofessional.
In the first round, while the interviewer was kind, he was in a meeting room where his colleagues interrupted him twice for a cake-cutting celebration. Despite him mentioning that an interview was ongoing, he eventually joined them, going on mute and turning off his camera for some time.
In the system design round, the interviewer asked me to open Notepad and start writing while he went to eat. He returned after 20 minutes and finally began asking questions. System design is supposed to be an interactive session, but he left me without direction. When he came back, he started challenging my notes while eating, with his camera off the entire time.
