Disorganized, unprofessional and disrespectful of my time. The first couple interviews were fine, but then the CEO disengaged and became busy with other matters.
They also requested a project without providing enough information to do so well. (A general note: this is an antiquated practice that few companies follow.) To cap it all off, they never scheduled time to follow up on it and discuss.
This was a very frustrating experience all around. Based on the interview experience alone, I lost interest in working at this company within a couple weeks.
