Since it was a senior role, I was scheduled a discussion with the CTO directly. I had high expectations on the company.But 10 mins into the discussion with the CTO, I was frustrated. The interviewer could not understand my project and did not have patience to listen what I'm trying to say. He behaved very rudely and often rubbed what i have written on the board. I decided there is no point in explaining further and did not concentrate further on the process.One of the worst ever experience.
