Before an actual interview they send you a home assignment to complete before. After it was submitted, i got a call from their HR, who basically asked me what did i think about submitted code. As i reply that i don't really understand the question and why is she asking me this, she tells me: "well, because your code is really bad!" and than she tells me good bye. This unprofessional behavior especially that comes from a HR person gave me an understanding that anyone who want to work in a respectful workplace should stay away from this company!
