Final interview with CEO

So I have been applying for roles in switzerland for a while. I have 2 offers with uber and eBay. i accepted both and i am due to start end of august. But i dont agree with the ,mission of both companies. So i dont want to work there unless I absolutely have to. And obviously i will eventually turn down one, either eBay or uber.

Theres a third company in the running. I see this field exploding in the next 2_3 years and im desperate to get on board. I understand and love the tech. I have blitzed 3 interviews and was invited to speak with the ceo for my final interview. It was meant to be yesterday morning at 10.30, i prepared so well, research was 110% on point. Ready to blast him with my knowledge, the new clients i have located and the opportunities I see for the company and how I can improve the sales of our product as its applications are a game changer for so many .

Anyway the time came for the interview, he messaged me saying he will be 15mins late. I said fine 30 mins passed and he was "away on skype. Sent him a message saying "Hi could you give me a time so we can reschedule the call to take? Thank you." Didn't hear back from him.

I later heard from the hr lady that he was on holiday in somewhere remote which is why he had trouble connecting.

And she will let me know when we can reschedule. I still haven't heard anything from them yet and tbh in getting impatient :/ .
My gf says fucc them they are jerking me around. My brother says maybe put my ideas on paper in a fun layout thats attractive to read and just send it to him as a pdf on skype.

What do you think?
