Domande di colloquio presso Integrated Control Technology

The first interview was rather shallow but mostly ok. I was then re-scheduled to a first interview by accident and once the interview started I said "nice to see you again" which is what triggered them to realise they had booked the wrong meeting. I was then given a task to create a presentation for the actual second interview which was in person. After spending 3 hours preparing and then presenting, I presented it to an incredibly disengaged exec, it's almost as if her mind was made up about me and that meeting being booked was another accident, at least that's how I felt. I then followed up via email twice and never heard back, not even a "thank you", a "sorry" or a straight "no"
