Carry Telecom interview questions

2 rounds of phone interview at first, then scheduled in-person interview the next day. 2 rounds of in-person interviews. First to mock a scene for phone call with a supervisor, then meet with HR and manager. Everything was good except last round interview, waited for a while without explanation, the questions are irrelevant and disturbing, the interviewers interrupted multiple times when I talked. Zero professional, no respect, mentally sufferings.

Interview process is not too complex, they do an initial phone screening, then invite you for an in-person interview at their location. You are then met with one of the team members who ask you questions about modems and routers and provides you some knowledge on their portal. Then you do a quick 5 min quiz, and wait outside until they call you in and ask you situational type of questions on how you would react with a customer on the phone.
