The first interview was pleasant and I had a great conversation with the person who was looking after the applications.
However, the next interview which was with one of the founders was a terrible experience. The interviewer did not listen to anything I said, interrupted me continuously, and it felt more like an interrogation than an interview or conversation. I can only imagine what working there/working with the founder would be like.
Needless to say, it left me feeling on edge and feeling uncomfortable. I didn't follow up with them and they didn't follow up with me.
My suggestion is to avoid.
