Delphi-US Software Engineer interview questions

The most unprofessional experience I have ever had. Had 2 calls setup with Dara the CEO or CTO, one of those First one, he emailed me and the recruiter saying he wanted to meet, then minutes before the meeting. just cancels. no nothing, wasted time Second one, we rescheduled and AGAIN cancelled 1 minute before the meeting with no email no heads up no nothing. The company has not respected anyone else's time other than their own. and after interviewing with MANY companies i have to say this is the ONLY company out of maybe 50-100 I've interviewed at in my lifetime that has had THIS much disrespect for it's candidates. I do NOT recommend, i can only imagine the kind of culture that exists if this is how they treat potential candidates
