I got referred by someone, and halfway through the hiring process I got contacted by the HR to apply for a job at Konux. They didn't know I was already interviewing there! I visited the office 3 different times to have 4 interviews (inconvenient). In 2 of those I was supposed to meet the CTO, but one time they said he was sick, the other time I started the interview with interviewer X then the CTO joined half an hour late and was constantly looking at his phone for 10 mins then just left, unfortunately he wasn't even listening to the conversation. So I ended up interviewing with X twice. 3 interviews were for knowing about my technical background and other behavioural insights (leadership, conflict resolution..etc). 1 interview was purely technical. The first part involved signal processing questions, the second part was a system design interview but the interviewer was a junior *electrical* engineer so it was very awkward. I had a hard time understanding the questions because the terms used by the interviewer to explain the software system had nothing to do with the SW Eng jargon. Even worse, the questions were asked in a slightly sarcastic/arrogant way. I did not see any senior technical person. Even though some people were really nice, my overall impression was that they're a very young (and arrogant) team who lack a great deal of professionalism, however they're doing a good job in terms of business development and penetrating a very old industry.
