MoPub interview questions

Take home coding challenge

It started with a phone screen, with situational questions asked in addition to the usual questions asked during a phone screen (why the company, position, etc etc). Then there was a second round of phone interviews, with similar questions asked but with a different person on the team. They seemed to like me, and scheduled me for an onsite, but the morning of the interview the interview was canceled on me with the premise of "the team being out that day". The recruiter did not try to reschedule and didn't respond to my emails and finally sent me a canned rejection email. I'm left with the notion that the company is probably not well organized because if they weren't interested they should have rejected me earlier in the process rather than schedule an interview and then give a flaky response then send a rejection email.
