Syscon System Engineer interview questions

Was given a time for a Zoom Web Conference meeting. They note it is crucial to be in the meeting 5 minutes before the meeting time. I was in the meeting 8 minutes before the meeting just to be sure, and my Zoom had bugged out. 4 minutes later after I was able to get in, I get a message from them stating "they found another candidate". Very unprofessional method of interviewing and the 4 minute right before the meeting late notice of "found another candidate" was top notch astonishing. I had already prepped for the interview and was excited to work with Syscon. Sounds like I, and possibly anyone in the future, may have dodged a bullet. Take the advice of other colleagues seriously, this place may be hiding shady practices despite its opportunities.
