Intercom Executive Assistant interview questions

Got to the second round and was asked to take part in an initial Skype Interview. After numerous emails confirming time etc. I was confident that I have the Skype address for the interviewer and I would call same at the time given. At the time I rang numerous times however I was blocked. Presumed that this person was snowed under with interviews so emailed to explain the predicament only to be told an hour or so later that I had not supplied my Skype address hence why I was not called. It was my first time taking part in a Skype interview for a job were I was supposed to be in the know about technology so to me it was not rocket science that I utilise the address GIVEN to me in the email from the interviewer.

Applied online for an operations coordinator and was contacted for a phone interview. Entire process took over a month. Phone interview was followed up by two additional phone interviews then spoke was advised I was being considered for a different position entirely (executive assistant). Next stop was an onsite interview which lasted roughly two hours with three different interviewers. Interview went great, felt like I connected with everyone and they kept emphasizing how they are in dire need to hire people. At the conclusion of interview I asked when I should hear back and they said within a few days. Over a week later I received an email stating I was not being considered for the position any longer. I replied to email and asked for some input on how I should improve for future interviews and never received a response. I was very disappointed with Intercom for their unpersonal follow up after spending over a month interviewing. This seems like a great company to work for but I feel they aren't sure what they want or need currently.
