Usual interview process, contact emails first, followed Teams meetings and then they asked to come to an office interview. Owner talked about company, then we chatted about previous work experiences, including a fair amount of technical details, how I would fit in if hired and what would be expected of me. Generally interviews went very well and they didn't give me any reason to think that they weren't happy with me during entire process. What I found completely unprofessional and rude is that after final interview they simply stopped any communications and didn't bother to update me on status of job application and yes I've chased for an update. This was particularly annoying since owner mentioned multiple times how he wanted serious interviewees that wont waste his time, yet he happily wasted mine :)
