After four rounds of interviews spanning 3 months, I received a generic rejection email from a do not reply inbox - not even from the HR representative I had repeated contact with. I spent a lot of time and energy preparing for the interviews just to be met with a generic rejection email. This made me happy I wasn’t selected since this shows how the company treats people. One of the interviewers also made fun of one of the systems I had on my resume and said how it’s so outdated that I should remove it - but I’m currently using that system at the company where I’m now employed lol. Just an example of how knowledgeable they are about the industry.
