I had a really great first interview with them. Asked the recruiter to send me some additional info. She said yes ofc but then never sent me anything. She also said she would get back to me a few days later. A week later I wrote her a follow-up email but she never replied. I am really disappointed and was really expecting at least an answer. I find this super unprofessional.

I had 6 rounds of interviews with different levels of managers in the company. I made it to the last round but was offered a position but it was not what I was looking for so i declined. It was a long interview process where I learned for how to answer tough questions for next opportunities.
