First of all, the CEO and COO are married and run the company together. The interview consisted of over 25 questions and the 3 interviewers kept going off topic. I felt like I was interrupting their staff meeting at times. It took 1.5 hours and I think the only reason they ended it was because they had another candidate coming in after me.
The COO seemed very particular and I felt like she might be checking my work at all times. She kept going over the very long list of tasks, one by one, repeating herself at times. They brought up another more senior role that they "hoped" whoever they hired would be a good fit for. I started to wonder what position I was being interviewed for and if they intended to hire me at a lower wage and then add responsibilities and duties later on down the road.
The CEO emailed me after the interview and asked me to return the next day on short notice. I managed to rearrange my schedule and come back under the impression they were ready to make an offer only to find out they had 17 more questions that they had not asked me the day before. By the end of the conversation I wondered whether or not I wanted the job.
