The moment the interviewer told me they worked with a php stack. I asked why they'd chosen to go with php given that the product was so new they could've chosen any newer tech. stack (JavaScript framework) and probably been better off. The interviewer didn't really response to my question.
The entire conversation with said person, was them talking at me for about 30 minutes. They said the company was going to try to pivot to developing some service surrounding their lock box service for the keys to get into people's houses for the dog walking.
It seemed very "directionless" and gave me a very bad taste in my mouth. They never got back to me or anything. Which was fine by me since I wasn't going to pursue them any further.
