There's not enough details here to give a fair analysis, or useful response, I think.<p>Seems to me that you assume a few things; (1) that the CEO is not insanely busy, (2) that they hung up on you a few times, when it could be any number of technical issues, (3) that they are not human, and able to maintain optimism and momentum through multiple disconnects without giving up.<p>Also seems to me that you wrote that tweet out of frustration, while if you had waited a day and let yourself cool down, you probably would have worded it differently, or not written it at all.<p>Of course, I have no idea what the tweet said, so this is just pure speculation.<p>As for what you could do differently, I'd say: be somewhere with better reception while doing phone interviews, and if the other party misses lots of appointments, assume that they're (a) new to their job/role, and/or (b) very busy - but they've still indicated that they want to talk to you, so actively remember that each time you feel let down.
