Technical interview was going well until the interviewer asked me a challenge in Spark. During that part, another interviewer joined us and started asking questions about the way I was developing, interrupting my thinking process every single time. As I continued the development of the task, he complained it was wrong and the way, saying the way I was trying to do wouldn't work. It was clear to me he didn't know spark well. I wasn't able to fully complete due to the interviewer bad behavior. Few minutes after the interview, I completed the challenge (as it was fresh in my memory) and sent by email, proving that the way I was doing would work. They didn't answer the email. For a few weeks I kept asking feedback from the recruiter who contacted me on Linkedin but he said he hadn't receive any yet. If the company doesn't respect the candidates, I imagine they don't respect the employees/contractors as well.
