I applied to a position in Kraków, Poland. I had a pre-screening call with a recruiter. She was very kind and respectful and explained the whole interview process and its steps.

Later, I moved on to another interview that was more technical. The interviewer asked me technical questions about Ruby and computer science in general, but his approach was very rude. He was sarcastic and rejected me by the end of the video call in a very unprofessional way.

Most of his questions were ambiguous and badly worded. When I asked for clarification, he basically responded to the question and moved to the next one.

Have you ever experienced a memory leak in a Ruby app?
