Topcon Positioning Systems Software Engineer interview questions

Phone call from HR planning interview, interview didn't have same 4 people as specified per earlier call. Pretty much no video cameras until midway for 1 guy. Another guy had poor audio quality and sounded like he was driving home. Only had C++ questions. No personal skills questions. That put me off straight away, was challenged but sounded like they didn't want to get to know me as a person and only wanted my technical skills. Also was told they'd get back first few days of the next week, took over two weeks to hear a response.
