Apadmi interview questions

Positive recruitment team and informal first interview. Invited for full on-site interview with presentation task to prepare. Spent a long time putting this together and preparing. Interview got rearranged less than 1 day prior, then they called a few days later to say there has been a "mix up" and the role has been filled. The job ad is still live so obviously they weren't being 100% truthful and in my case seem to have messed me around.

First stage was a simple 30-45 minute interview about yourself. Including an overview of any projects you've done and how you went about them, but mainly about your own personality and work ethic. They also asked what programming languages you are most comfortable with and why, which languages you prefer over others, etc. Then the second stage (if invited to it) is an in person interview, which for some reason I didnt clock it would be more like an assessment centre. More interview questions and a system design challenge (UML diagram in my case, but they dont expect you to know about it really, just do it however you prefer). Thats about it, really nice people and a really straightforward process, not too technical.
